WASHINGTON - Wizards forward Andray Blatche will be out three to five weeks because of a strained left calf.
Washington coach Randy Wittman made the announcement before Monday night's game against Chicago.
Blatche was injured in Saturday's win in Charlotte. After an MRI exam, he was advised to stay off his feet.
Blatche missed three games earlier this month with a sprained right shoulder. He was averaging 10 points and seven rebounds per game.
Since Wittman became coach last week, Blatche had been coming off the bench. To help replace him, Washington recalled centre Hamady Ndiaye from Iowa of the D-League.
The Bulls will be without Richard Hamilton (right thigh) and Luol Deng (left wrist). It's the fifth straight game Deng has missed.
