Miami Dolphins quarterback Tua Tagovailoa has been medically cleared to play and is set to start against the Arizona Cardinals on Sunday. This follows his recovery from a concussion sustained in Week 2, marking his third concussion in three seasons. Head coach Mike McDaniel confirmed that Tagovailoa has completed the NFL's Return to Play protocol after participating in two full practices this week. The Dolphins, who have struggled with a 1-3 record in his absence, will also need to activate him from IR, likely involving a roster move with another quarterback. Tagovailoa's return is anticipated to significantly enhance Miami's offensive capabilities, especially if top receivers Tyreek Hill and Jaylen Waddle can also play. Prior to his injury, Tagovailoa had completed 64.5% of his passes for 483 yards in two starts this season.
