Information on the ex boxer tony sibson?

Answer 1

fought for the world title twice. against Marvin hagler and frank tate.

the tate fight was controversial for two reasons.

first, the IBF still had 15 round fights, but the BBB of C followed the WBA a few months earlier and banned any 15 round fights on british soil. and it wasn't until the 11th hour that it was decided the fight was gonna be for 12 rounds.

second, some idiot let off tear gas in the arena just prior the the fight.
