We don't yet know who will start at quarterback for the New England Patriots against the Buffalo Bills this weekend, but Rex Ryan doesn't sound concerned.

"I can sit back and say I don't care who plays quarterback, because [Tom] Brady ain't," Ryan said. "I don't care who plays quarterback. Steve Grogan can play quarterback. If [Bill] Belichick's playing quarterback, we're coming after him, I promise you that."

Ryan made the comments after Buffalo's 33-18 win over the Arizona Cardinals -- the team's first win of the season.

Tom Brady has one more game left on his four-game suspension. Jimmy Garoppolo (shoulder) and Jacoby Brissett (thumb), who combined to start the first three games, are uncertain for the Bills game.
