The Tennessee Titans could be without quarterback Jake Locker, who suffered a separation of his left, non-throwing shoulder for the second time this season on Sunday in a loss to the Houston Texans.

Titans coach Mike Munchak is in wait-and-see mode regarding Locker's availability this week against the Minnesota Vikings after an MRI revealed no structural damage to the shoulder.

“It's similar to last time,” Munchak said via TitanInsider. “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.”

If Locker cannot go, the Titans will turn to veteran Matt Hasselbeck, who will likely get the bulk of the practice reps, at least early in the week, even if Locker's shoulder responds to treatment.
