fights were low blows played a key role

Does poosy count? If yes then Judah hitting Floyd in his poosy.

 

Exactly.

 

Not always the differences in the fight result, but certainly affected the action greatly and took away from the performance of the infraction committing boxer:

Tyson/Holyfield 1.

Tyson won the first round, Holyfield won 2,3,4. Tyson won the fifth with some huge bodyshots and uppercuts. Holyfield looked to be tiring.

Tyson starts off the 6th really strong.

Low blow by Holyfield, headbutt by Holyfield, Tyson is cut. And then a KD by Holyfield.

Tyson seemed jaded for the rest of the fight.

Holyfield also landed the same 'combination' against Dokes as well

 

Bellew-Cleverly is another one.

I think Bellew won the first 3-4 rounds until a low blow by Cleverly and then Clev took over the rest of the fight.

 

this belongs on the mount rushmore of fights where low blows played a part in the outcome. :deal
