Fresh off remaining as players union president during All-Star weekend,Derek Fisher’s first initiative apparently was to re-instate himself on an NBA team.

Not with the struggling Dallas Mavericks, the team he bailed on in December and the only one willing to sign him in late November. Fisher signed Monday with the Oklahoma City Thunder, the championship contender he joined late last season that conveniently again has an opening for a veteran point guard with a history of making clutch shots.

The 38-year-old southpaw who won five titles in two stints playing alongside Kobe Bryant, signed a veteran’s minimum deal with the Mavs on Nov. 29 on the heels of Dallas benching Darren Collison. Fisher immediately took over as the starter until he asked for and received his release on Dec. 22 so he could spend more time with his family, as he explained in a prepared statement.

Owner Mark Cuban did not reply to multiple emails on Monday, but one league source said the best way to describe the mood of the Dallas front office is “agitated.” The source said that Fisher and his representatives never contacted the Mavs during his decision-making process to discuss a possible return to Dallas, the team that, in good faith, initially signed him.
