The Bears announced practice squad moves Wednesday, replacing one offensive tackle with another.
Chicago signed OT Perry Dorrestein, an undrafted rookie, and terminated the practice-squad contract of OT Josh Davis. Dorrestein started 22 games for the University of Michigan and appeared in 31 games for the Wolverines.
The Bears signed Davis to the practice squad on Tuesday. He spent the preseason with the team after signing as an undrafted free agent out of Georgia.
