Jake Locker has no structural damage to his left, non-throwing shoulder and coach Mike Munchak says the Titans quarterback will be day-to-day this week. Locker dislocated his shoulder Sunday early in a 38-14 loss to Houston when sacked by Texans cornerback Glover Quinn in an injury Munchak said happened from the quarterback slamming back into the turf, not from the hit itself. He watched the rest of the game with his arm in a sling and had an MRI exam Monday. Munchak said the Titans (1-3) will know more in the next couple days whether or not Locker will play Sunday at Minnesota (3-1). ''It's similar to last time,'' Munchak said of Locker, who originally hurt his shoulder in the season opener against New England. ''The MRI was very similar. It popped out, and they popped it back in. He's real sore right now, so they're just waiting a couple of days to get a full examination.'' Munchak said the Titans won't necessarily rest Locker just to give the shoulder time to heal to prevent him from another dislocation. ''Obviously, rest is better than playing football with any injury. Not playing football would be good for all of us, but I don't know that he would sit out for that reason,'' Munchak said.
