MONDAY, 11:07am: The Mavs officially announced, via press release, that they have signed James for the rest of the season.
SUNDAY, 9:14pm: The Mavericks have guaranteed the contract of Mike James for the remainder of the 2012/13 season, tweets Dwain Price of the Fort Worth Telegram. James' second 10-day deal, signed January 18, was set to expire on Sunday night. The Mavericks made no secret of their plan to sign James for the rest of the year. The veteran point guard has averaged 3.3 points and 11 minutes in 9 games in Dallas.
Eddie Sefko of the Dallas Morning News wrote earlier today that the decision on James was expected to come down tonight, and that the perception of Rodrigue Beaubois would likely play a part in the decision. Marc Stein of ESPN confirms the deal, via Twitter, and says that the Celtics would have had interest if the Mavs passed.
