Klitschko back in US, meets unbeaten heavyweight Jennings

NEW YORK _ It’s difficult to tell if Wladimir Klitschko has a tougher time holding up all his championship belts or defending them in the ring. That’s where he will be Saturday night, in Madison Square Garden for the first time in seven years, when he puts his four heavyweight championships on the line against unbeaten Bryant Jennings. Klitschko is on a 19-bout winning streak and this will be his 27th title fight, matching a heavyweight record set by Joe Louis.
