The Cleveland Cavaliers suspended center Andrew Bynum indefinitely Saturday for conduct detrimental to the team.

In addition, the Cavs will begin aggressively looking to trade Bynum, sources told ESPN.com.

Cleveland has until Jan. 7 to decide if it will guarantee his contract for the rest of the season. Bynum signed a two-year, $24 million deal with the Cavs last summer, but the team-friendly contract included only $6 million in guaranteed money.

The decision to suspend Bynum was made Friday, sources said. Bynum did not travel with the team to Boston for Saturday's game against the Celtics.

"It's a terrible situation internally with our team," All-Star guard Kyrie Irving said before the Cavs faced the Celtics. "It's something we have to get over."

It is unclear what led to Bynum's suspension. Cavs coach Mike Brown did not disclose any details regarding the suspension but expressed concern for his players.

"I'm worried about the guys in the locker room," Brown said prior to Saturday afternoon's game. "It's simple as that. In our business, there are a lot of ups and a lot of downs throughout the season.

"So what you do as a head coach is keep moving forward. Any time you look back on anything or dwell on anything, is wasted energy from the guys in the locker room, which is obviously very important."
