CLEVELAND (AP) -- Cavaliers center Anderson Varejao had surgery to repair a split leg muscle, an injury that could sideline him two more months.

Varejao had the operation on Thursday at The Cleveland Clinic. The team said he is resting comfortably and will be kept overnight. Varejao, the NBA's leading rebounder, has been sidelined since getting hurt against Toronto on Dec. 18. His injury was initially believed to be just a bad bruise, but further testing revealed that the quadriceps muscle tore near his right knee.

He is expected to miss at least six weeks. Varejao, one of the league's hardest working and hustling players, has missed more than 100 games over the past three seasons with injuries.

Varejao was averaging 14.1 points and 14.4 rebounds when he got hurt.
