Cook scores 3 TDs to help Bills rout Dolphins 31-10, Tagovailoa leaves with concussion

James Cook caught a touchdown pass and ran for two scores and the Buffalo Bills routed Miami 31-10 on Thursday night, with Dolphins quarterback Tua Tagovailoa leaving early because of a concussion.

Tagovailoa left in the third quarter after colliding with defensive back Damar Hamlin and hitting the back of his head against the turf. Tagovailoa was quickly ruled out with the concussion, casting doubt on his season after a history of dealing with head injuries.

Josh Allen, playing with a glove on his left non-throwing hand after hurting it in Buffalo's opener, completed 13 of 19 passes for 139 yards. He's 12-2 against the Dolphins and the Bills are 14-2 against Miami since coach Sean McDermott’s first year as head coach in 2017.
