In the past few years, Dereck Chisora has been one of boxing's most notorious bad boys. When he fought Vitali Klitschko in Germany in February 2012, he slapped the champion at the weigh-in, then spit water in younger brother Wladimir's face in the ring just prior to the fight.
After staging a surprisingly competitive battle against the injured Klitschko, Chisora engaged in a brawl with fellow Brit David Haye at the post-fight press conference, touching off an international incident. Five months later, Chisora lost to Haye by TKO in the fifth round.
In 2013, Chisora won four straight fights by stoppage, including a strange sixth-round finish of Malik Scott which saw the American lose track of the count after being dropped by a big overhand right.
Despite his sometimes rambunctious attitude, Chisora has shown definite signs of maturing as a fighter. Since his 2011 loss to Tyson Fury, his weight has consistently been within a good range. His defense has shown signs of improvement as well.
So long as Fury and Chisora both win on Saturday night, a rematch between them would be a very relevant fight. The winner would be well-positioned for a challenge against Wladimir Klitschko.
Kevin Johnson is a late replacement in this bout for undefeated Andriy Rudenko, who pulled out with an injury. Johnson challenged Vitali Klitschko for the world title in 2009, but has appeared on the definite downside of his career over the past two years.
In June 2012, he dropped a three-round fight to Tor Hamer in the Prizefighter tournament and lost by unanimous decision to Fury in December of that year. Last December, he looked positively sluggish in dropping a decision to 14-3 Christian Hammer.
A win here for Johnson would put him back on the path toward relevancy in the division. However, it will take a much better effort than he was able to muster his last time out against Hammer.
