NASHVILLE, Tenn. (AP) -- Titans middle linebacker Colin McCarthy remains in a walking boot and will be evaluated Saturday to determine if he can play Sunday against the Buffalo Bills on his sprained right ankle.
McCarthy is improving. Titans coach Mike Munchak said Friday they decided not to risk aggravating the linebacker's high ankle sprain.
The Titans (2-4) have to decide whether or not to rest McCarthy, who missed three games earlier this season after originally hurting his ankle in the season opener.
McCarthy said Monday this injury could linger all season long if he continues to play on it.
Munchak said they could try resting McCarthy to give his ankle time to improve more.
Tennessee's defense has struggled this season ranking 28th overall with McCarthy in and out of the lineup.
