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.
