Titans quarterback Vince Young is questionable for Sunday's game against the Rams with a right knee injury. He re-aggravated his sore right knee during Tennessee's loss to Indianapolis last Sunday and he tweaked it again in practice on Thursday. "He didn't practice today," Titans coach Jeff Fisher said, adding that missing practice "will not have anything to do with whether or not he plays. He understands the game plan and got at least half of the preparation."
