3:10pm: The Bobcats have officially acquired Warrick in exchange for Carroll, confirms B.J. Evans, the team's vice president of communications (Twitter link).
With Carroll not part of the Bobcats' rotation, president Rod Higgins viewed the move as a no-risk opportunity to upgrade the club's frontcourt depth, according to Rick Bonnell of the Charlotte Observer (Twitter link).
3:02pm: There is a trade "in the works" between the Bobcats and Hornets, according to ESPN.com's Marc Stein. Stein reports (via Twitter) that the two sides are negotiating a swap involving Matt Carroll and Hakim Warrick, though it's not clear if a deal is imminent or just being discussed.
Both Carroll and Warrick are playing on similar expiring contracts, with Carroll earning $3.5MM in the final year of his deal, while Warrick is earning $4MM for the Hornets. Warrick also has a team option for next season, but it's not believed to include any guaranteed money, and almost certainly won't be picked up. Either way, New Orleans would be saving a little salary in the event of a deal.
A change of scenery could be beneficial for both players, who aren't seeing much playing time this season. After appearing in 53 contests for the Bobcats last season, Carroll has played just six minutes in one game this season. Warrick, meanwhile, saw seven minutes of action in his lone game for the Hornets last week.
