Arthur Abraham must show that his previous win against Robert Stieglitz was no fluke.
Abraham's time as a top contender looked to be all but over after his horrendous showing at the Super Six World Boxing Classic. He lost three of his five fights, culminating with a thorough defeat to Andre Ward. It was about as one-sided as any decision could be.
The Super Six was a rather sobering event for a previously unbeaten fighter.
A fight with Stieglitz was the last title chance Abraham would likely ever have. He risked falling into obscurity with yet another loss.
Instead, Abraham put on the performance of a lifetime, considering where he had been previously.
His fight with Stieglitz back in August was extremely good. Both went right after each other, with Abraham winning a unanimous decision and the WBO super middleweight title.
In terms of a narrative, you couldn't ask for any more as a fight fan. On one hand, you've got Abraham carrying a massive chip on his shoulder. On the other is an extremely motivated Stieglitz who will be looking to atone for his previous defeat.
When you couple that with the quality of their first fight, you've got a great night ahead.
Few could have predicted that Abraham would be able to claw his way to victory against a very game Stieglitz. Some might be of the opinion that Stieglitz did in fact win the fight.
That's why it's so vital for Abraham to come out the more decisive victor this time around.
Boxing's history is littered with guys who put it all together on one night and beat the champion. Then they failed to recreate that kind of performance and never hit those heights again.
Having held the IBF middleweight title, it's not as if Abraham is simply a scrub who got lucky against Stieglitz in Berlin. He's still a good fighter. It's just a matter of exactly how good he is.
Let's not forget, though, exactly how bad Abraham performed at the Super Six. It was a golden opportunity for him, and he flushed it right down the drain.
Wins against Pablo Farias, Mehdi Bouadla and Piotr Wilczewski aren't going to convince anybody that Abraham is completely back. The victory against Stieglitz made people take notice.
Aside from simply losing, the worst thing Abraham could do is to win another closely contested fight. He needs to distance himself from Stieglitz over the 12 rounds.
Knocking him out would be even better.
