IBF/IBO Heavyweight Champion Wladimir Klitschko and no. 3 contender Calvin Brock will announce their November 11 title clash at a press conference at Madison Square Garden on Tuesday afternoon, September 19, at 12 noon. The highly anticipated heavyweight championship contest will be promoted by K-2 Promotions in association with Main Events, and televised by HBO Sports and RTL. The fighters, promoters, HBO and MSG representatives will be in attendance for the formal announcement. This will be Klitschko’s first defense of the title he captured from Chris Byrd in Mannheim, Germany on April 22. It will be Brock’s first title opportunity, and his sternest ring test as he puts his unbeaten record on the line.
