The club also signed linebackers DeDe Lattimore and Terrell Manning to the practice squad, while waiving defensive end David Bass and terminating the practice squad contracts of defensive end Roy Philon and receiver Rashad Ross.
Interestingly, Frey started at nickel corner for the Bears in their 31-24 loss Sunday to the Carolina Panthers, and contributed six tackles while playing a role in the club storming to a 21-7 second quarter lead on the strength of three takeaways. Frey stripped Panthers rookie receiver Kelvin Benjamin after an 18-yard catch, and recovered the fumble with the Bears trailing 7-0.
A three-year veteran, Frey played in 19 games with seven starts with the Bears, posting 73 tackles and two pass breakups to go with his forced fumble and recovery against the Panthers.
In Frey’s absence, look for the Bears to move Sherrick McManis into the slot corner role. McManis has missed the last three games due to a quadriceps injury. Demontre Hurst is also an option at that position.
Louis-Jean, meanwhile, is an undrafted rookie free agent out of Boston College, where he played in 21 games over three seasons, contributing 36 tackles, an interception, four pass breakups and a pair of forced fumbles.
Bass played in 13 games with one start over the past two seasons with the Bears.
