The Chicago Bears signed offensive tackle Roger Gaines and defensive end Cheta Ozougwu to the practice squad on Tuesday, and terminated the practice squad contracts of quarterback Jerrod Johnson and offensive tackle Jamaal Johnson-Webb.

Gaines entered the NFL as an undrafted free agent with the Baltimore Ravens out of Tennessee State.

Ozougwu, meanwhile, played in two games with the Bears last season and contributed three tackles and another stop for lost yardage. It’s likely the Bears added Ozougwu to provide depth along the defensive line because the club could be looking to move defensive end Corey Wootton inside on occasion due to the loss of defensive tackle Henry Melton, who suffered a torn ACL on Sunday in the team’s win over the Pittsburgh Steelers.

Ozougwu signed a reserve/future contract on Jan. 2, but the Bears waived him on Sept. 1.

Ozougwu's move to the practice squad could mean the Bears might be looking to promote practice squad defensive end Aston Whiteside, who spent some time in training camp also working inside at defensive tackle.

The Bears also held tryouts for defensive tackles Landon Cohen and Daniel Muir, according to an NFL source.
