Thad Lewis has said that he is "pretty familiar" with the Cincinnati Bengals' defense.
The quarterback will make his first start for the Buffalo Bills against the AFC North side this weekend, having been promoted from the practice squad following EJ Manuel's knee injury.
The 25-year-old told the Toronto Sun: "I'm pretty familiar with them, from having been in Cleveland for two years. So I've studied them four times, actually. And you've got to go off what you see. No guessing.
"Just make sure you see the right things and play, and you'll be all right. They play as a unit, but the defensive line is something.
"They can disrupt you. So if we can do a good job of running the football and getting the ball out like we should be, we'll be fine."
Lewis played once for the Cleveland Browns last season, completing 204 passing yards in the process.
