I commented on a Joshua Klitschko thread the other day re a rematch and the old saying - knock a guy out and you'll knock him out even quicker win the rematch.

Got me thinking how many fighters have actually avenged a knockout loss. So without cheating I'm going to say I can only recall the following ones , both Lewis. And the second one wasn't even a knockout.

Lewis v Rahman
Lewis v McCall

Any more ? No googling.......
