Despite adding two free agents at the position, the Rams re-signed DT Gary Gibson to a one-year deal.
Gibson started all 16 games last season at right defensive tackle. He recorded 18 tackles and two passes defensed.
St. Louis signed former Colts DT Daniel Muir and former Broncos DT Justin Bannan during free agency. The three will compete to start at right defensive tackle next to Fred Robbins.
