NASHVILLE, Tenn. (AP) -- The Titans' Jake Locker has no structural damage to his left, non-throwing shoulder and coach Mike Munchak says the 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. He watched the rest of the game and had an MRI exam Monday.

Munchak says the Titans (1-3) will know in the next couple days whether Locker will play Sunday at Minnesota (3-1).

The coach says Locker surprised everyone with his quick recovery hurting the same shoulder in the opener. Munchak says Locker held the ball too long on a three-step drop.

Tennessee's bigger issue may be fixing a defense that has given up a league-worst 151 points -- 20 more than any other team.
