"Titans quarterback Vince Young was limited in practice Friday because of an ankle injury, raising doubt that he will play Sunday against the Dolphins.

Kerry Collins took the bulk of the snaps, giving every indication that he would be the starter. Collins also worked after practice with new receiver Randy Moss.

Young, who did not practice Tuesday or Wednesday, is questionable on the injury report and is a game-time decision, Coach Jeff Fisher said. Young was limited in practice Thursday and Fisher "backed him down" Friday.

"Vince was limited. We'll warm him up (Sunday) and see how he does,'' Fisher said.

Young re-aggravated his left ankle injury during the Oct. 31 game against the Chargers, did not finish and sat out practices during the bye week. He was initially hurt in the Oct. 18 game against the Jaguars then sat out the Oct. 24 game against the Eagles.

Collins started against the Eagles and has played in half of the eight games. Sunday could be an on-field reunion with Moss — both were Raiders in 2005."
