Orton, who completed 22-of-39 passes for only 193 yards, suffered a toe injury during Thursday's 22-9 loss to the Dolphins, ESPN's Mike Rodak reports. The Buffalo offense had just two real possessions before halftime, largely because those two drives took a combined 15 minutes, 51 seconds. Orton was okay in the first half, when the Bills used a slew of short passes and their running game to keep the Miami pass rush at bay. Everything fell apart after Buffalo's second drive of the third quarter, as both Orton and the offensive line struggled terribly for the rest of the game. It's unclear how much blame Orton deserves for the safety he took on a questionable intentional ground call, but he was without doubt inaccurate on the few downfield throws he tried. He also missed some easier passes, and the Bills were complete unable to run in the second half. Orton's second straight poor performance will lead to questions about his job security, though it's only fair to point out that he was facing excellent defenses behind a poor offensive line both times. When asked after the game if he's thought about replacing Orton with C.J. Manuel, Bills head coach Doug Marrone said, "Right now that hasn't crossed my mind."
