Behanan can transfer to another school and is eligible to play the second half of next season. He may also decide to play professionally.
"We lost a really terrific man in many respects," coach Rick Pitino said at a press conference. "Away from the lines, he just did not do the right things, over and over and over. The university has gone to the met for him, in giving him every opportunity to make it here. It's come to a difficult detour in his road. It's set our basketball team back immensely."
Pitino said it is unlikely that the school will reinstate Behanan.
"None that I can see," he said. "This is a university policy that has been stretched to the limits."
Behanan was suspended indefinitely in October for violating university and team rules, but Pitino did not give specifics. Behanan was reinstated less than a month later. He missed just one game.
Since his reinstatement, Behanan's play regressed from last season, including his production and minutes.
In his final game for Louisville, Behanan went scoreless in 20 minutes in Saturday's loss to Kentucky. He averaged 7.6 points and 6.3 rebounds per game this season after averaging 9.8 points and 6.5 rebounds last season.
"We're all let down by this," Pitino said.
