NASHVILLE, Tenn. — The Tennessee Titans have added defensive back Curtis Riley to their active roster and have officially placed guard Chance Warmack on injured reserve.

Titans coach Mike Mularkey said Wednesday that Warmack would undergo surgery to repair a torn tendon on his right hand and would be placed on injured reserve. The move was officially announced Thursday.

The Titans also announced Thursday they had signed guard Karim Barton to their practice squad.

Riley signed with the Titans last year as an undrafted free agent out of Fresno State, but he spent the entire season on injured reserve.

Barton, who is 6-foot-3 and 313 pounds, signed with the Philadelphia Eagles in 2014 as undrafted free agent out of Morgan State. He spent most of last season on the Houston Texans’ practice squad.

The Titans host the Oakland Raiders on Sunday.
