ORCHARD PARK, N.Y. (AP) - Shawne Merriman finds himself back in Buffalo eager to resume playing football, while also feeling a little red-faced over his, well, red face.

Bills coach Chan Gailey says he expects Merriman to be in good enough shape to contribute when the Bills face the Titans Sunday.

"As long as he is in playing shape and everything goes well this week and he gets back into the flow of things, he is probably going to be right there on Sunday afternoon giving us some help."

Preparing for his first practice with the Bills in two months on Wednesday, the pass-rushing specialist sheepishly explained why his face was conspicuously sunburnt. It happened about 10 days ago when he fell asleep on the beach after finishing a workout at his home in Miami.

With winter around the corner, he won't be needing any sunblock in Buffalo, where the three-time Pro Bowl selection is getting yet another chance to kick start what's been a stalled career.

The Bills (3-3), who host Tennessee (2-4) on Sunday, re-signed Merriman this week to provide veteran depth to an injury-depleted defensive line.

Merriman says it's good to be back.

"If they didn't think I could play defensive end, they wouldn't have brought me back. You know I'm happy not only to contribute, but to kind of pick up where I left off and do what they need me to do."
