The Dolphins lost convincingly 31-10 to the Bills and made matters worse by losing Tua Tagovailoa.

The Dolphins quarterback was diagnosed with a concussion after a terrifying collision on a fourth-down run when he hit his head on Bills defensive back Damar Hamlin. Tagovailoa suffered a series of concussions in 2022 that led him to consider retirement.

Tagovailoa threw three interceptions, with Ja’Marcus Ingram having two of the interceptions. He returned one 25 yards on the Dolphins’ first possession to set up James Cook’s first of three touchdowns. Ingram later had a 31-yard pick-six. Christian Benford had the other pick for the Bills, setting up a 19-yard field goal drive.

Ed Oliver and Von Miller both had a sack for the Bills.

Tagovailoa went 17 of 25 for 145 yards with a touchdown, and his replacement, Skylar Thompson, was 8 of 14 for 80 yards. Thompson beat out Mike White for the backup job, and after his release, White signed with the Bills’ practice squad.

The Dolphins could look to add White to their active roster if Tagovailoa misses playing time, which seems likely given his history.

Cook’s touchdowns came on a 17-yard reception and runs of 1 and 49 yards. He had 11 carries for 78 yards and one catch for 17 yards.

Josh Allen completed 13 of 19 passes for 139 yards and a touchdown, while the Bills managed just 247 yards.

The Bills have defeated the Dolphins in 12 of their last 13 games, including the playoffs.
