Wladimir Klitschko has decided to keep boxing despite suffering a beating at the hands of Lamon Brewster in their WBO heavyweight showdown on Saturday. "The fight is lost," he told Germany's Bild newspaper: "But I definitely won't end my career this way.
"I was in control, then in the second round, I noticed something was wrong - the strength drained out of my body.
"My legs were like rubber. I now need to find out with certainty what was wrong with me."
After the fight, Klitschko was taken to hospital for a precautionary brain scan and he is set to undergo tests to find out whether he might have a medical problem.
There have been widespread calls for the former Olympic champion to retire.
