The Chicago Bulls say guard Michael Carter-Williams is expected to miss between four and six weeks after an MRI revealed a bone bruise in his left knee and a left wrist sprain, the team announced Tuesday.

Carter-Williams was hurt during Monday's victory against the Brooklyn Nets.

Acquired in the preseason from the Milwaukee Bucks in a trade for Tony Snell, he went down clutching his knee during the second quarter after attempting to block Sean Kilpatrick's shot.

It was initially feared that the injury was a torn ACL, sources told ESPN. However, Carter-Williams underwent an MRI on Monday, and the results showed the bone bruise, along with the wrist sprain.

Carter-Williams was averaging six points, four assists and 3.5 rebounds in the first two games for the Bulls. He suffered the injury after playing just five minutes against the Nets.
