The Dolphins are placing QB Tua Tagovailoa on IR for his fractured ribs. That means he'll miss at least the next 3 contests. The team reportedly hopes to get the QB back for Week 6. Until then, it's Jacoby Brissett ... which means it's also time to queue up fantasy defenses playing against Miami. That's the Raiders this week, then the Colts and Buccaneers. If Tagovailoa makes it back for Week 6, he'd get a nice pair of matchups with Jacksonville and then Atlanta.
