Tua Tagovailoa ruled out of Dolphins’ playoff game vs. Bills

MIAMI GARDENS, Fla. (AP) — Miami Dolphins coach Mike McDaniel says quarterback Tua Tagovailoa remains in the NFL’s concussion protocol and has been ruled out for Sunday’s playoff game against the Buffalo Bills. Tagovailoa has not yet been cleared to return to football activities. The Dolphins are preparing for rookie Skylar Thompson to be their starter when they face the Bills for the third time this season. Backup Teddy Bridgewater is working his way back to full strength after dislocating his pinky finger.
