Sixers forward Marreesse Speights will be out 6 to 8 weeks with a partial tear of the medial collateral ligament in his left knee, the team said today.

Speights was injured in the fourth quarter of the Sixers' loss at Chicago on Saturday night and did not return to the game.

He underwent an MRI exam when the team returned from Chicago and was examined by team physician Dr. Jack McPhilemy.

The injury is a substantial blow to the Sixers because Speights has been one of the team's best players early this season. He is averaging 13 points and 6.4 rebounds per game in 23.4 minutes per game off the bench.

"We are discussing options and looking at a list of possible replacements, but don't see quick move," team president and general manager Ed Stefanski said in an email to the Daily News today.

The Sixers have 13 on their roster and 12 available players. Primoz Brezec will be active for the first time since the season opener when the Sixers resume play Wednesday at home against Charlotte.
