the luckiest punch in boxing history was lennox lewis' left hook in the 7th round of his world title defence again frank bruno at wembley stadium

after dominating the action throughout Bruno had the canadian pinned in the corner, lewis closed his eyes put his head down and took a hopeful wild swing, a momentary lack of concentration from bruno and the punch landed in the perfect spot on the point of the jaw

If it had landed anywhere else bruno would have finished his man

but can you think of any other lucky punches that have, maybe, turned a fight in such a way?
