After suffering his third official NFL concussion, Tua Tagovailoa has been issued a stern warning by the Miami Dolphins, raising concerns about his future with the team due to his recurring injuries.

Miami Dolphins quarterback Tua Tagovailoa is doubtful for Week 18 due to a hip injury he suffered earlier this month. Tagovailoa was also doubtful last week for a game against the Cleveland Browns and was eventually listed as inactive.

He needs to be available,’ Dolphins general manager Chris Grier said, adding that he’s ‘very confident’ in his franchise quarterback. ‘He needs to know how to protect himself.’
