Ratliff out 4-6 weeks

MILWAUKEE -- Theo Ratliff underwent surgery on his left knee today and will be sidelined a minimum of four to six weeks, the Lakers announced. Team orthopedist Steve Lombardo performed the 30-minute procedure this morning. Ratliff played eight games and averaged 0.3 points and 1.6 rebounds before missing the last two games because of tendinitis. The Lakers could use Andrew Bynum's services right about now, but there's no firm date for his return to the practice court after he underwent offsesaon right knee surgery.
