Dolphins' Jay Ajayi helped off practice field: 'My arm was cramping'

Miami Dolphins running back Jay Ajayi was helped off the field Friday at training camp with an apparent arm injury.

As Ajayi left the field, he appeared to favor his right elbow, according to Miami Herald's Adam Beasley.

Ajayi later tweeted that the reason for his practice departure was nothing serious, saying: "it's fine. My arm was cramping lol."

The Dolphins selected Ajayi in the fifth round of the draft. Once considered a possible Day 2 pick, concerns about the health of Ajayi's knees likely pushed him down the board.

Should Ajayi miss significant time, Damien Williams would likely be elevated to the role of backup to starter Lamar Miller.
