Bentley, 26, is a former third-round pick of the Lions back in 2012. He had one year remaining on his four-year, $2.649 million rookie contract when the Lions elected to cut him loose back in June.
In 2014, Bentley was limited to appearing just two games after he sustained a season-ending ACL injury in earlier September.
During the 2013 season, Bentley appeared in 13 games for the Lions and recorded 29 tackles and five pass defenses. Pro Football Focus had him rated as the No. 82 cornerback out of 110 qualifying players that year.
Louis-Jean, 22, signed on with the Bears an an undrafted free agent out of Boston College last year. He was unable to make the team’s final 53-man roster coming out of the preseason, but he later signed to the team’s practice squad and wound up appearing in a number of games last season.
The Bears elected to re-sign Louis-Jean to a two-year contract back in February, but he was unfortunately among their roster cuts at the start of the season.
In 2014, Louis-Jean recorded nine tackles and a pass defense over the course of nine games for the Bears.
