Seattle’s and Geno Smith’s new center was Tagovailoa’s snapper the previous two seasons. He’s seen him concussed before.

Tua Tagovailoa is gone from the Miami Dolphins‘ active roster. But he hasn’t really gone anywhere. It’s been just a week since Tua suffered his third concussion in the last 24 months, but he’s already embraced the only role he can for the next five weeks: Unofficial coach.

Tua Tagovailoa, who suffered a concussion in the Buffalo game, is placed on injured reserve by the Miami Dolphins.
