The Tennessee Titans defense suffered a blow Tuesday when cornerback Ryan Mouton injured his Achilles' tendon during practice.
Mouton will have an MRI on Wednesday, but The Tennessean reported it's likely he is out for the season. He had to be helped off the field by trainers and was later seen in the locker room wearing a walking boot and on crutches.
Mouton, a third-round pick out of Hawaii in 2009, appeared in 14 games for the Titans last season.
