Tennessee Titans starting quarterback Jake Locker left Sunday's game against the Houston Texans with an apparent left shoulder injury.
On 3rd-and-7 midway through the opening quarter, Glover Quin came untouched on a safety blitz and sacked Locker for an 8-yard loss. While Locker was going down, Houston defensive end J.J. Watt hit him with the crown of his helmet directly on the shoulder.
Locker stayed on the ground for several minutes before heading back to the locker room with his left arm tucked against his chest.
Locker also suffered a left shoulder injury during Tennessee's season opener against the New England Patriots.
