NASHVILLE, Tenn. — Titans rookie cornerback Ryan Mouton hurt his left ankle this morning and had to be carted off the practice field. Coach Jeff Fisher did not have an immediate report on the severity of the injury.

Mouton is the Titans' second pick in the third round out of Hawai‘i. The 5-foot-9 rookie had been competing to be the team's backup nickelback, or fifth defensive back in passing situations. Mouton also has been working as a backup outside cornerback and handling both kickoff and punt returns.

The rookie intercepted a pass and ran it back 29 yards for a touchdown in the Titans' 27-20 exhibition win last weekend over Tampa Bay.
