Which boxer had the least luck in a series of fights against the same opponent?

I'm going with Watson against Eubank.

I thought Watson won the first fight but somehow Eubank got the decision.

In the rematch Watson had an unassailable lead. His head caught the ropes as he went down in the 11th round.

If he had gone down in another part of the ring and not landed on the ropes he wouldn't have sustained the injury that led to the fight being stopped and he would have won the fight.

Instead he lost the fight, his career was finished and he almost died as a result.

I can't think of anyone more unlucky.
