Mike Tyson seen wearing Neck Brace: "'I was damaged before boxing'

if you were an avid MT fan, you would have noticed an increase of his "head rolling" he does at the announcements. It almost looked compulsive, all of a sudden he'd jerk his shoulders and roll his head around real quick. Sometimes he'd do it in the middle of the fight. He'd do this alot in post-fight interviews too.

This behavior increased as he got older.
