The Bears made a series of moves to shuffle up their practice squad on Tuesday.
The Bears signed running back Raheem Mostert and terminated the contracts of offensive lineman Laurence Gibson and running back Senorise Perry.
Mostert, 24, entered the NFL as undrafted free agent out of Purdue in 2015. He appeared in 11 games for the Cleveland Browns (2015), Baltimore Ravens (2015) and Miami Dolphins (2015), returning 19 kickoffs for 530 yards (27.9 average). Mostert spent the 2016 preseason with the Browns before he was waived and signed to the New York Jets practice squad ahead of Week 1.
