Golden Bears coach Cuonzo Martin said in a statement Thursday that the injury is ''very unfortunate.'' He says it's difficult to predict when Rooks will return, though typical recovery time can take up to a year.
The 7-foot Rooks averaged 1.6 rebounds and 1.3 points in seven minutes as a freshman. He played in all but two of Cal's first 28 games before missing the final seven contests with a stress reaction in his left foot.
Martin says Rooks will start his rehabilitation program immediately.
