EAST RUTHERFORD, N.J. -- EJ Manuel was a surprise healthy scratch for Thursday night's game against the New York Jets but remains the Bills' backup quarterback, coach Rex Ryan said after Buffalo's 22-17 win.

Josh Johnson served as Tyrod Taylor's backup Thursday but did not play.

"What happened was, we had a short week," Ryan said. "And Josh was really -- he knew the game plan going in. ... Preparing, all that playing. So he knew the thing like the back of his hand. Probably knew it better than Tyrod did."

Ryan explained that Johnson had more time to work with offensive coordinator Greg Roman since he hadn't had to prepare as much for the Bills' previous game.

In addition, Roman had faced Todd Bowles' teams before, when Roman was the San Francisco 49ers' offensive coordinator and Bowles, the Jets' first-year coach, was the Arizona Cardinals' defensive coordinator.

Manuel was a healthy scratch for the first two games this season before the Bills traded veteran quarterback Matt Cassel to the Dallas Cowboys. When Taylor injured his knee in Week 5, Manuel made two starts for the Bills, losing both.
