The Tennessee Titans have lost a cornerback for the season with an Achilles injury.

Jim Wyatt of the Tennessean reports that cornerback Ryan Mouton suffered the Achilles injury in Tuesday night’s practice.

Although a diagnosis won’t be made until his MRI on Wednesday morning, he’s expected to need season-ending surgery.

Mouton was a third-round draft pick in 2009.

At least two other players have been lost for the season to Achilles injuries in the last week: Bengals linebacker Roddrick Muckelroy suffered a ruptured Achilles’ tendon at practice on Saturday, and Browns punter Reggie Hodges tore his Achilles’ tendon at practice on Tuesday.
