Awful, awful news for a great kid who was going to be a real key for this team.

Here's the release from U of L:

University of Louisville junior guard/forward Mike Marra suffered a torn anterior cruciate ligament in his left knee in the Cardinals' victory over Lamar on Sunday and will miss the remainder of the season.

Marra went down with 12:17 remaining in the second half of the Cardinals' 68-48 victory over Lamar. A magnetic resonance imaging test at Jewish Hospital on Sunday night revealed the damage. Surgery will be scheduled later and the normal recovery time from an ACL reconstruction is 9-12 months.

Marra scored six points in each of Louisville's first two games. He averaged 6.2 points and two assists as a sophomore last season, starting 11 games.
