Fairley was injured when he clashed heads with teammate Lamarcus Joyner while trying to make a tackle.
Barron and Fairley have played in all 15 of St. Louis’s games this season, while Westbrooks has appeared in 12 games. Barron is the Rams’ leading tackler. Fairley is on a one-year, $5 million contract after spending four seasons with the Lions and has taken a back seat to Aaron Donald and Michael Brockers on the interior of the defensive line.
