Forward Vladimir Radmanovic is out eight weeks after falling on a patch of ice Saturday in Park City, Utah, and sustaining a separated right shoulder.

Radmanovic told the Lakers he was walking when he slipped. Some pro sports contracts ban players from taking part in activities involving significant risk of injury, such as skiing and snowboarding. It is not known if Radmanovic's contract contained such language.

An MRI exam and CT scan conducted Monday in Los Angeles confirmed the injury as a separated shoulder.

"It's the latest incident in a season-long series of injuries," Lakers spokesman John Black said. "Guys are going to have to step up and fill the void."

Radmanovic, 26, has been a disappointment in the first season of a five-year, $30.2-million contract. He was slowed by a hand injury early in the season and is averaging only 6.9 points and 3.4 rebounds a game.

His tendency to freelance in the triangle offense led Coach Phil Jackson to refer to him as a "space cadet" in December. More recently, Jackson criticized Radmanovic's penchant for shooting unnecessarily because "it just might feel good."

Radmanovic's absence will mean more playing time for Brian Cook, and it could cause the Lakers to take a harder look at 41-year-old Scottie Pippen, who said he would like to come out of a three-year retirement. Kobe Bryant has endorsed Pippen for consideration by the Lakers, although the former Chicago Bulls forward said he would prefer to play for Miami.
