Bears star edge rusher Khalil Mack has returned against the Browns after missing most of the first half with a foot injury -- and he's already made another sack.
Mack recorded an early sack on Baker Mayfield, but left a short time later.
He returned from the locker room after being treated and stood on the sideline for the remainder of the first half.
Mack jogged onto the sideline before the third quarter started. He was handed his helmet and returned to the field for Cleveland's first possession.
