New allegations tell us what made Garrett go off the way he did.

During the Browns and Steelers game, the camera catches Garrett striking Pittsburg Steelers qb Mason Rudolph with his helmet.

NFL rules states, the use of any equipment is considered a weapon.  And would be an immediate suspension.

Since the incident, Garrett claimed that Rudolph called him a racial slur.  But didn’t specify what it was.
