ORCHARD PARK, N.Y. (AP) — Quarterback Kyle Orton agreed to sign with the Buffalo Bills in addressing the team's lengthy search for an established veteran to play behind second-year starter EJ Manuel. A person familiar with the deal confirmed the agreement on Saturday, and spoke on the condition of anonymity because the Bills have not announced the move. With Manuel also out with a knee injury at the time, the Bills scrambled to acquire Lewis in a trade with Detroit and sign Matt Leinart, who was then cut after struggling in his preseason debut. The first-round pick finished 4-6 and missed time because of three separate knee injuries. The Manuel-led starters combined to score four field goals and two touchdowns in five preseason games.
