The Miami Dolphins will be without quarterback Tua Tagovailoa for at least the next four games after he was placed on IR. Tagovailoa suffered another concussion, which was the third known one in his NFL career. There have been concerns regarding his future ...

Tagovailoa isn’t the only Dolphin dealing with an injury. Running back Raheem Mostert did not play against Buffalo last week due to a chest injury. He is not expected to play against Seattle. Offensive lineman Terron Armstead will return to the field Sunday after missing the season’s first two games with a torn rotator cuff.

None of this matters if Tua is cleared to play. If he’s not cleared, however, the Dolphins will owe every penny of the guaranteed money — possibly if not probably with no insurance money to refund the cash or to secure salary-cap credits.
