The St. Louis Rams have added two backup quarterbacks - Austin Davis and Brady Quinn - to provide depth after Sam Bradford's torn ACL left them with Kellen Clemens as their only option under center, according to Ian Rapoport of NFL.com.
Davis was signed by the Rams as an undrafted free agent out of Southern Mississippi after the 2012 draft but was released before the start of the 2013 season. Quinn was released by the Jets on Monday and has served as a backup for several teams throughout his career. He has 20 starts spread throughout his six years in the league.
