Titans quarterback Jake Locker hurt his right foot in the second quarter against the Jacksonville Jaguars,
Locker ran an option play and was hit by Jaguars linebacker Russell Allen. Locker limped back to the huddle and turned the ball over on the next play when he was so hobbled he couldn't hand off cleanly to Chris Johnson. The Jaguars recovered.
The Titans quarterback went to the locker room and was replaced by Ryan Fitzpatrick.
Officials said Locker's return was questionable. But the quarterback, who sprained his right hip and knee Sept. 29 against the Jets and missed two games, returned to the sideline by the start of the fourth quarter wearing street clothes. He also was on crutches with his right foot in a walking boot.
Rookie center Brian Schwenke also hurt his right ankle and was replaced by Chris Spencer. Receiver Damian Williams hurt his quadriceps and also was using crutches when he returned to the sideline.
