Klitschko is a cut above Charr

Vitali Klitschko retained his WBC heavyweight crown in disappointing fashion last night when a bad cut sustained by challenger Manuel Charr ended things in the fourth round.

Rumours have been circulating for some time that this could be the giant Ukrainian's swansong but he'll surely want to bow out in a grander manner than this.

That said, Klitschko did dominate the contest before its premature end.

In the second round, Charr had also found himself looking up from the canvas after Klitschko detonated a left hook.

And it was a similar blow which opened up the laceration over Charr's right eye two rounds later.

"I'm disappointed I didn't manage to win the fight with a real knockout," Klitschko said.

"Sadly, it was the doctor's decision. We both wanted to continue the fight."
