The Dolphins will be without Tagovailoa for at least three more games after he suffered a concussion in Week 2. NFL rules state that any player on injured reserve must miss at least four games, but it is unclear when Tagovailoa might return. McDaniel has insisted that there is no timeline and that the team is simply focused on getting Tagovailoa healthy.
Tagovailoa remains in concussion protocol but was able to travel with the team to Seattle.
Thompson wasn't the only Dolphins starter knocked out of Sunday's game. Cornerback Kendall Fuller left with a concussion, and left tackle Terron Armstead was ruled out with an eye injury.
