HOUSTON (AP) -- Tennessee quarterback Jake Locker injured his left shoulder after being sacked by the Houston Texans in the first quarter on Sunday and his return is questionable.
He returned to the sideline in the second quarter in street clothes with his left arm in a sling.
Locker was sacked by Glover Quin and thrown to the ground. He remained there for a few minutes in pain while trainers attended to him. He eventually got up and walked off the field before being taken to the locker room.
Matt Hasselbeck came in for Locker on the next series.
Locker injured the same shoulder in Tennessee's season-opening loss against New England.
