Last time Miami collided with the Buffalo Bills, the Dolphins’ season got thrown completely off course.Quarterback Tua Tagovailoa sustained a concussion in the third quarter of a 31-10 home loss to Buffalo back on Sept. 12, and he missed the next four games. The Dolphins lost three times during that span, averaging 10 points in those four contests.With Tagovailoa now back in the fold, Miami will attempt to get back on track when it heads to Orchard Park, N.Y., on Sunday afternoon for a rematch with the Bills.Tagovailoa made his return last Sunday, completing 28 of 38 passes for 234 yards and a touchdown in a 28-27 setback against the Cardinals. Chad Ryland booted a 34-yard field goal as time expired to complete Arizona’s rally from a nine-point fourth-quarter deficit.Although the Dolphins (2-5) fell further behind first-place Buffalo (6-2) in the AFC East, Tagovailoa believes there is still time for Miami to make a push.”Seventeen games. That’s a long time. A lot of games,” Tagovailoa said. “So whether we’re counted out or we’re not, it doesn’t matter. We’re going to continue to play football. … Anything’s possible.”So we’re going to continue to trust each other, lean on each other, believe in each other and we’re going to go do it (against the Bills).”Buffalo quarterback Josh Allen knows the Bills can’t take the Dolphins lightly, no matter what the standings say.”They’ve got some real, real playmakers on the defensive side of the ball. I know their record doesn’t indicate it, but they’re playing really good football right now,” Allen said. “So, we got to be ready for whatever they can throw at us. Got to have a good week of practice and again, make adjustments in-game and go from there.”
