Tennessee Titans coach Mike Munchak said Friday the team will likely decide by Saturday morning who will start at quarterback for Sunday's game against the visiting San Francisco 49ers.
Quarterback Jake Locker and running back Shonn Greene are list on the team's injury report as questionable.
Locker returned to practice Wednesday for the first time since injuring his right knee and hip against the New York Jets on Sept. 29. Locker was wearing a brace on his knee and was moving with a noticeable limp while taking snaps and throwing.
Ryan Fitzpatrick is also being considered as a starter for Sunday.
Greene returned to practice Wednesday as well after missing the last five games with a knee injury.
