Ryan hopes cornerback Ronald Darby (groin) will return after missing one game. Linebacker Nigel Bradham (ankle) has missed four games and is uncertain to play Sunday. Rookie right guard John Miller (ankle), safety Bacarri Rambo (shoulder/knee) and cornerback Ron Brooks (neck) are also battling nagging injuries.
"We will see how that goes during the week," Ryan said.
"We know we are facing a team that is red hot," Ryan said. "This team is a complete football team. No surprise they have the record they have."
It's as close as it will get for the Bills, who will miss the playoffs for the 16th straight season.
The Bills have already placed several starters on injured reserve: defensive tackle Kyle Williams (knee), cornerback Stephon Gilmore (shoulder), safety Aaron Williams (neck), and wide receivers Robert Woods (groin) and Percy Harvin (knee/hip) on injured reserve. Right tackle Seantrel Henderson (illness) is on the non-football injury list.
"I think guys do get revved up," Ryan said. "This is your last shot at it this year, so you get to play against a team that has everything riding on it."
The coach's new team has a chance to spoil the playoff hopes of his old team in Sunday's season finale.

But they can still affect the AFC postseason picture.
Ryan acknowledged that Bills players may be motivated by the opportunity to keep their AFC East rivals out of the playoffs.

Kick coverage specialist and reserve wide receiver Marcus Easley became the latest player placed on injured reserve. Easley dislocated his left kneecap and sustained a compound fracture while covering a punt during Sunday's 16-6 victory over the Dallas Cowboys.
"Just us getting a win against a good football team is great," Ryan said. "I don't care if we play East Carolina, you want to get a win, period."
"This is a major, major injury," Ryan said. "(Doctors) say he will come back from it. So it is just going to take time, but he should be fine.
Ryan ruled out tight end Charles Clay (back) for a fourth straight game and said the Bills may be cautious about letting Pro Bowl running back LeSean McCoy (knee) return from a one-game absence.
"This will be a playoff game for us," left guard Richie Incongnito said after Sunday's game.
Most of the injured Bills played in Buffalo's 22-17 win on Nov. 12 at the Meadowlands.
