The Bears placed veteran safety Antrel Rolle on injured reserve on Monday, prematurely ending the player’s first year with the team. Rolle has been battling injuries for much of the season and has missed the previous four games specifically with a right knee injury.

Rolle, 32, signed a three-year, $11.25 million deal in free agency this offseason and was brought in with the hope of solidifying a Bears secondary that was in bad shape last year. But Rolle injured his ankle in the Bears’ Week 4 victory over the Oakland Raiders, and then injured his knee in practice on Nov. 20, per head coach John Fox.

Rolle has only appeared in seven of the team’s 13 games this season.

The Bears could have used Rolle’s veteran leadership in the secondary, but there have been some pleasant surprises along the way. Rookie fifth-round pick Adrian Amos has had an impressive first season and Chris Prosinski has done a fair job filling in for Rolle. Prosinski will continue to start in Rolle’s stead for the remaining three games of the season.
