Things keep getting worse for the Titans, no matter who the quarterback is.

Starting quarterback Zach Mettenberger just left the field with an apparent right shoulder injury.

And then deposed quarterback Jake Locker came into the game, and immediately threw an interception on his first pass attempt.

Mettenberger was in obvious pain after being drilled into the ground by Texans defensive end J.J. Watt, and has walked to the locker room for more tests. But he doesn’t look like a guy who will be coming back to a game his team trails 24-7.
