NASHVILLE, Tenn. (AP) The Tennessee Titans are unsure whether a trio of players will be able to play Sunday when they visit the winless Cleveland Browns.

Running back DeMarco Murray, who tweaked his hamstring for the second time this season Monday night, returned to practice Friday but was limited in his workouts. He will be a game-time decision.

Tight end Delanie Walker (calf injury) was added to the injury report Thursday and was held out of Friday's practice. He is listed as questionable. The Titans will also monitor the progress of linebacker Derrick Morgan (abdominal strain), who was limited in his workouts for the second straight practice
