Chark didn't participate in Wednesday's practice due to injured ribs.
Chark handled his typical workload in last week's loss to the Steelers, but he may have been playing hurt during the contest. He'll look to upgrade his participation by Friday to have a shot to play Sunday against the Browns, who will be without No. 1 cornerback Denzel Ward (calf). If Chark is able to play, he'll catch passes from his third quarterback of the year, as Mike Glennon has been named the Week 12 starter.
