Adonis Stevenson, 2013: 4 fights, 4 wins, 4 knockouts. Sergey Kovalev, 2013: 4 fights, 4 wins, 4 knockouts. Both these lead-fisted ring animals captured world titles last year. Stevenson holds the WBC light heavyweight championship and Sergey Kovalev holds the WBO version. These guys, both heavily showcased on HBO last year (including once on the same card), are seemingly on a collision course. The no-nonsense, gunslinging Kovalev would be a sure test for Stevenson's questionable chin. However, Stevenson has displayed the ability to box on the move, so if he's able to come in and out of range effectively, he could in turn ask questions of Kovalev's chin. In the mean time, Stevenson is scheduled to fight Andrzej Fonfara in late May, so a potential clash with Kovalev - who doesn't have a fight scheduled at this present time - wouldn't be until the late summer or autumn at the earliest.
