2:30pm: Jones' unwillingness to accept a D-League assignment prompted the Mavs to cut ties, as Marc Stein of ESPN.com reports.
1:53pm: Dallas has waived former first-round pick Dominique Jones, tweets Alex Kennedy of HoopsWorld. Since the move comes after March 1st, the guard will be ineligible to play for another team in the postseason this year should someone sign him or claim him off waivers. The Mavs tried to trade him at multiple points earlier this season, but never found an offer they liked.
Jones is making a guaranteed $1.277MM in the third season of his rookie-scale contract, signed after the Mavs drafted him with the 25th overall pick in 2010. In October, the team declined its $2.3MM option for next season, and though GM Donnie Nelson didn't rule out re-signing him in the summer, it appeared to signal an end to the South Florida product's tenure in Dallas. Jones has posted 4.0 points and 2.9 assists this season, career-high marks for a player who has seen little playing time. He's averaging 11.7 minutes per contest this year, but has only appeared in five games since New Year's Day.
The Mavs had been carrying a full 15-man roster, so the move gives them the flexibility to sign someone else, perhaps on a 10-day deal. Dallas is in 11th place in the Western Conference but still has a reasonable shot to make the postseason, since the team is just three and a half games back of the Jazz for the eighth playoff spot.
