Varejao, the NBA's leading rebounder, will miss his seventh straight game. He hasn't played since Dec. 18 when he injured the knee against Toronto.
Varejao returned to practice in a limited role Monday, but hasn't gone through contact drills. He said last week that he still felt pain when he tried to bend or push off on the knee and he thought the injury needed another week to heal.
Varejao is averaging 14.4 rebounds and 14.1 points.
Cavaliers guard Daniel Gibson will miss his second straight game because of a concussion.
