NASHVILLE, Tenn. (AP) -- Tennessee quarterback Matt Hasselbeck will start his third straight game when the Titans visit Buffalo on Sunday, and injured Jake Locker could be healthy enough to return in a week.

Doctors checked Locker's left, non-throwing shoulder again Monday. Coach Mike Munchak said he didn't have the results, but that the quarterback is healing up enough that he may start throwing later this week.

There is no quarterback controversy. Munchak says Locker will play when healthy. Locker dislocated his shoulder Sept. 30 in a loss at Houston.

The Titans (2-4) worked out for an hour Monday after a weekend off following their 26-23 win over Pittsburgh.
