Tennessee Titans linebacker Zac Diles' status is uncertain after he hurt his right ankle and was carted off from the sideline during a 35-34 win over the Buffalo Bills on Sunday.
Coach Mike Munchak had no immediate update on the severity of Diles' injury. Munchak would only say that Diles' injury initially appeared to be more serious than an injury sustained by reserve linebacker Patrick Bailey, who hurt his chest while covering a kickoff in the third quarter.
Diles was hurt when he was attempting to tackle running back C.J. Spiller on the Bills first possession. Diles was leaning to his left, when he lost his footing and his right ankle twisted beneath him.
Diles slowly limped off the field after being tended to by Titans trainers, and was then driven off from the sideline.
Diles was starting in place of Colin McCarthy, who missed his fourth game with an ankle injury.
The Bills lost right guard Chad Rinehart early in the third quarter after he hurt his left ankle blocking during a run by Spiller. A Titans player fell on the back of Rinehart's leg, forcing Rinehart to be carted off the field.
Coach Chan Gailey had no update on Rinehart's status following the game.
Buffalo was already minus starting offensive linemen Kraig Urbik (knee) and Cordy Glenn (knee). Rinehart was replaced by third stringer Sam Young.
