This is all I could find: That makes me think it's more like a hereditary medical condition than an actual injury.
Second-year receiver Erik Ezukanma was placed on the reserve/non-football injury list because of a neck injury that flared up Sept 29th. The Dolphins claim Ezukanma, who Miami was using in a Deebo Samuel-like role as a receiver carrying the football on gadget plays, had a pre-existing neck injury from his time at Texas Tech that got re-aggravated recently.
