Rasheed Wallace has officially decided to retire, TNT’s David Aldridge reported on Thursday night, citing a league source. The decision was expected following the Celtics’ Game 7 loss to the Lakers in the NBA finals. After the game, Doc Rivers said, “I don’t know if Rasheed will ever play again. He’s one of them. I think he took that out on the floor with him.” Wallace had $12 million and two years left on his contract, which he signed last summer.

Wallace most recently averaged 5.3 points and 4.6 rebounds during the finals, including a Game 7 start. It was a bounceback from an inconsistent regular season in which he posted 9.0 points and 4.1 rebounds while shooting 28.3 percent from 3-point range in 79 games.

Wallace was selected by the Bullets with the fourth overall pick in the 1995 NBA Draft. He earned four All-Star selections and won a championship in 2004 with the Pistons. Wallace ranked sixth in games played among all active players.
