Purdue senior forward Robbie Hummel re-tore the anterior cruciate ligament in his right knee during Saturday's morning practice and will miss the 2010-11 season.
"This is obviously disappointing for Robbie, as well as our team, since he worked so hard to return from the tear he suffered in February," coach Matt Painter said in a statement. "As he begins rehab and recovery, we'll persevere together and provide Robbie with all the support possible. I have no doubt he'll continue to play a pivotal role this season as a leader of our team."
Hummel averaged 15.7 points and 6.9 rebounds last season before tearing his ACL in a game at Minnesota. Without Hummel, the Boilermakers advanced to the Sweet 16.
Purdue was primed to contend for a national championship this season with Hummel, a versatile, All-America candidate, and All-Big Ten classmates JaJuan Johnson and E'Twaun Moore.
