Tua Tagovailoa was replaced at quarterback by Ryan Fitzpatrick during the fourth quarter of the Miami Dolphins’ game against the Denver Broncos on Sunday.

The Dolphins were down 20-10 with under 10 minutes remaining when Fitzpatrick took over. There were questions about whether Tua was replaced due to performance or injury reasons. Tagovailoa entered the game with a foot injury, and CBS’ announcers speculated both reasons factored into the QB change.

There were further questions about whether the tackle Tagovailoa took on a sack led him to be replaced.

Tagovailoa’s left leg/foot appeared to get bent awkwardly on the sack, which was the sixth one he had taken in the game.

The rookie quarterback was not having a good game. He was 11-of-20 for 83 yards and a touchdown prior to being replaced. The Dolphins entered the contest on a five-game winning streak.
