The Knicks have officially signed Quentin Richardson for the remainder of the season, the team announced today (Twitter link). Since the club released Solomon Jones yesterday, there is an open roster spot, meaning no corresponding move will be required to clear room for Richardson.

When the Knicks waived Jones, I speculated that perhaps James Singleton's CBA clearance issues had been resolved, since Singleton was the player the team initially wanted to sign. It doesn't appear that was the case, but Richardson, like Singleton, isn't a big man, so it seems the team is comfortable with its frontcourt depth heading into the postseason.

Richardson, who spent four seasons with the Knicks earlier in his career, is still being paid by the Magic, who released him prior to the start of the season. The 33-year-old spent two fairly unsuccessful seasons in Orlando, averaging just 4.5 PPG  and an 8.4 PER in 105 contests for the Magic in 2010/11 and '11/12.

Because he hasn't signed with an NBA team since October, Richardson remains playoff-eligible, though I can't imagine him playing much of a role for the Knicks in the postseason.

Despite indications this morning that the Nets/Knicks opener in Brooklyn tomorrow would proceed as planned, the game will be postponed due to the effects of Hurricane Sandy, tweets Greg Anthony of CBS Sports and NBA TV. It's not clear yet whether the Knicks' Friday game at Madison Square Garden or the Nets' Saturday game in Brooklyn will be played. For now, however, it seems the debut of the Barclays Center will have to wait as the city continues to recover.

Here are a few more notes from around the league:

• Prior to reaching an agreement on a contract extension for Stephen Curry today, the Warriors and Curry had been discussing a deal with an annual salary ranging from $8.5-10MM, according to Marc J. Spears of Yahoo! Sports. Golden State upped its offer following Ty Lawson's four-year, $48MM deal with the Nuggets.
• The Bulls are monitoring the free agent market in anticipation of being able to add a minimum-salary contract later in November, says Aggrey Sam of CSNChicago.com. Quentin Richardson is one player under consideration, according to Sam.
• The fact that the Bulls haven't been able to pair a second star with Derrick Rose yet hasn't been due to lack of trying, executive VP of basketball operations John Paxson said on ESPN 1000 Chicago (link via ESPNChicago.com).
• The Grizzlies never considered undergoing what GM Chris Wallace calls a "voluntary rebuild" this summer, writes Ronald Tillery of the Memphis Commercial Appeal.
• One of the main lessons Cavaliers owner Dan Gilbert learned from the LeBron James saga was not to let a star player leave in unrestricted free agency without getting anything back for him, according to an Associated Press report.

Perhaps the most surprising training camp cut was Quentin Richardson, whom the Magic waived despite $5.438MM worth of guaranteed money on his contract for the next two seasons. The surprising play of DeQuan Jones, who appears to have made the team on a non-guaranteed deal, pushed Richardson out the door, writes John Denton of Magic.com. There's plenty of other news about players coming and going today, in advance of the 4:00pm Central time deadline for teams to let go of camp invitees so that they clear waivers before rosters must be down to 15 players.

• While an earlier report indicated the Lakers were expected to waive Darius Johnson-Odom, Dave McMenamin of ESPNLosAngeles.com believes the guard still has a shot to make the team (Twitter link).
• The Heat are at the regular-season roster limit of 15 players, but Ira Winderman of the South Florida Sun-Sentinel doesn't rule out the possibility that the team could pick up one of the guys that other teams let go in the past few days (Twitter link). 
• John Rohde of The Oklahoman shares insight from Thunder coach Scott Brooks on the team's cuts and its decision to keep DeAndre Liggins. "With DeAndre, we felt that his size, his athleticism, his defensive toughness is something we are intrigued with and we like," the coach said.
• Sam Amico of Fox Sports Ohio saw Hollis Thompson play Thomas Robinson evenly while both were in college last season, and believes Thompson, whom the Thunder let go today, should wind up with another NBA team (Twitter link).
• The Rockets still must waive three players, and Jonathan Feigen of the Houston Chronicle points to reasons why Jon Brockman, JaJuan Johnson and Gary Forbes could be the ones to go.
• HoopsWorld's Derek Page checks in with Mavs waiver claim Eddy Curry, and wonders whether his 11 points, seven rebounds and three blocks in Friday's preseason game against the Bobcats might have been enough for him to win a roster spot.
• Shavlik Randolph and Steven Gray are likely out of the discussion to make the Wizards opening night roster, but Earl Barron is making a late push for a spot, as Michael Lee of The Washington Post examines.

The Magic have waived Quentin Richardson, Justin Harper, and Chris Johnson, a team official told Josh Robbins of the Orlando Sentinel (via Twitter).  Richardson will be owed $5MM over the next two years while Harper is guaranteed $762K for this season.  Johnson's deal was non-guaranteed.

Richardson was set to earn $2.627MM this season and held a $2.808MM player option for 2013/14 that now becomes guaranteed after being waived.  The guard came to Orlando on a widely panned four-year deal worth more than $10MM in the 2010 offseason.  In two years with the club, the 32-year-old averaged 4.4 PPG and 2.9 RPG.

Harper, 23, was taken with the 32nd overall pick in the 2011 draft by the Cavs before being traded to Orlando for two future second-round selections.  The big man saw time in 14 games for the Magic last season.

It may not be many more days until our long national Dwightmare is over. Yesterday's reports on Howard suggested talks involving the Magic, Nets, and Cavaliers were getting serious, and that Orlando plans to make "one last sweep" around the league before deciding whether to accept the Nets' offer. While we wait to see if anything is agreed upon today, here are the latest rumblings on the Howard front:

• Chad Ford's ESPN.com report includes some more slight tweaks to the framework described below. Ford adds Chris Duhon to the list of players headed to the Nets, suggests the Magic would receive one fewer first-rounder (a total of three instead of four), and says the Cavs would receive $3MM in cash.
• Ford's report, along with tweets from the Cleveland Plain Dealer and Ken Berger of CBSSports.com, suggest that the Cavs and Clippers still aren't entirely on board. The Plain Dealer tweets that talk of a deal getting close is premature, while Berger says the Clips haven't agreed to anything yet and are one of several potential fourth-team facilitators in the mix (Twitter links).

Earlier updates:

• It "sounds like" the Magic, Nets, and Cavs have found a fourth team to facilitate the Howard blockbuster, tweets Alex Kennedy of HoopsWorld. According to Chad Ford of ESPN.com (Twitter link), that team is the Clippers -- Los Angeles would acquire MarShon Brooks in exchange for a lottery-protected first-round pick, which would go to the Magic.
• In addition to the framework described by Wojnarowski below, the Magic would also receive Armon Johnson from the Nets in the proposed deal, tweets Ken Berger of CBSSports.com, who cautions in a second tweet that pieces could still move in or out.
• Before either team agreed to any deal, Magic doctors would need to examine Brook Lopez and Nets doctors would need to examine Dwight Howard, says Adrian Wojnarowski (Twitter links).
• Adrian Wojnarowski of Yahoo! Sports had the details of the proposed three-team blockbuster: The Nets would receive Dwight Howard, Jason Richardson, and Earl Clark, the Magic would receive Brook Lopez, Damion James, Shelden Williams, and Luke Walton, and the Cavs would receive Kris Humphries, Sundiata Gaines, and Quentin Richardson. The Nets would also send three first-round picks to the Magic, one to the Cavs, and would send MarShon Brooks to a fourth team to acquire another first-rounder for the Magic.
• A source tells the Cleveland Plain Dealer that a deal involving the Cavs looks doubtful at this point (Twitter link).
• Don't expect a Howard deal to go down today, tweets Brian K. Schmitz of the Orlando Sentinel.  Getting Andrew Bynum from the Lakers would be Orlando's best deal, but the club is concerned about his knees holding up, Schmitz tweets.
• Kris Humphries would be seeking a four-year deal with the Cavs and wouldn't be willing to sign a one-year deal, tweets Marc J. Spears of Yahoo! Sports. Sign-and-trades require a three-year minimum, but only one year needs to be guaranteed. Frankly, with a rumored 11 to 14 players involved in the proposed deal, and many of them needing to be involved via sign-and-trade, I'd be surprised if Humphries was the only player that could hold things up.
• We should expect resolution on the Nets/Magic talks pretty soon, according to Alex Raskin of HoopsWorld, who says Brooklyn intends to move on if a deal can't be consummated in the near future.
• The Nets are willing and able to take on Jason Richardson's salary in the proposed three-team deal, tweets Chris Broussard of ESPN.com.
• Bob Finnan of the News-Herald hears that the Nets want one of the Cavaliers' first-round picks in the trade, which could be a dealbreaker for Cleveland.
• Jason Lloyd of the Akron Beacon Journal and J.A. Adande of ESPN throw some cold water on the Howard talk. A source tells Adande that "to act like it's almost done is overblown" Twitter link), while Lloyd continues to hear that there's "isn't much to it" on the Cavs' end (Twitterlinks).
• Numerous reporters, including Fred Kerber of the New York Post (Twitter link), are noting that the talks between the Nets, Magic, and other teams have "a lot of moving parts," but that progress is being made. According to Kerber, the odds are better than 50/50 that Howard is sent to the Nets.
• Magic brass are meeting this morning to discuss whether to pull the trigger on the proposed Nets/Cavs deal, tweets Alex Kennedy of HoopsWorld.
• A fourth team may be entering the mix to take MarShon Brooks, according to Adrian Wojnarowski of Yahoo! Sports, who adds that up to 14 players could be involved (Twitter link).
• Although the Cavs look like the Nets' best bet to find a taker for Kris Humphries, Brooklyn has found traction on two other possible scenarios, says Wojnarowski.

6:13pm: According to ESPN.com's Marc Stein, Golden State has moved away from talks of a three-team deal that would send Monta Ellis to Orlando. In a tweet, Stein says the Warriors are far more interested in assembling a package to offer Milwaukee for Andrew Bogut. Stein went on to say that the Warriors would be unwilling to part with Ellis, even if it meant getting rid of Andris Biedrins' contract, one of the worst in the league. According to an ESPN report by both Stein and Chris Broussard, the Magic will continue to spend the next 48 hours seeking various options on how they can add an enticing player to keep Dwight Howard happy. If they can't make a splash, they'll then spend the last 24 hours before the deadline looking at all their trade options.

1:57pm: The Magic, Hornets, and Warriors are discussing a three-way trade that would send Monta Ellis to Orlando, multiple league sources tell Jarrod Rudolph of RealGM.com. According to Rudolph, Warriors players being discussed include Ellis, Andris Biedrins, and Dorell Wright, while Magic players mentioned include Ryan Anderson, J.J. Redick, Hedo Turkoglu, Quentin Richardson, and Daniel Orton. Taking into account the Warriors' reported interest in Chris Kaman, the Hornets' involvement likely means Kaman would be going to Golden State if a deal was reached.

Although nothing is imminent, talks are ongoing, says Rudolph. I'd be surprised to see the three clubs work out an agreement, given all the moving parts involved, not to mention the presence of the league-owned Hornets -- with David Stern still acting as the team's de facto owner, he'll have the opportunity to turn down any trade he doesn't feel benefits the team.

Reports in recent weeks have also indicated that the Warriors aren't looking to move Ellis unless they can acquire Dwight Howard. So it would be unexpected to see them move the Western Conference player of the week to Orlando for non-Howard assets. As Sam Amick of SI.com tweets, Joe Lacob seems unlikely to help the Magic keep Howard, since the Warriors owner covets the star center himself.
