Seahawks QB Matt Hasselbeck suffered an undisclosed injury, which appears to be a back or rib injury, just before halftime of today’s game against the 49ers.

Buffalo quarterback J.P. Losman is expected to start for injured Trent Edwards against the New York Jets, Minnesota quarterback Tarvaris Jackson is expected to start for injured Gus Frerotte at Arizona, and Seattle quarterback Seneca Wallace is expected to start for injured Matt Hasselbeck at St. Louis.

As much as they would like their quarterback situation to change, it hasn’t. For the third straight week, Seahawks quarterback Matthew Hasselbeck will not be sufficiently recovered from his back injury to start, a Seattle official said Wednesday.

Charlie Frye got his turn at quarterback for the Seahawks last Sunday. Seneca Wallace could get his turn at quarterback Sunday night at Tampa. Seahawks coach said Wallace and Frye would split reps at practice this week and the more prepared quarterback would play.

The Seahawks will place WR Logan Payne on the injured reserve list with a torn knee ligament in his right knee, and have lost Seneca Wallace for a month with a calf injury.
