He lost the belt for his failure to fight mandatory challenger Sergiy Derevyanchenko. The situation started when Golovkin's fight against Alvarez for this past May 5 was canceled after Alvarez withdrew from the fight after testing positive for clenbuterol.
Considered to be one of the best fighters of his generation, Golovkin won the IBF middleweight title by beating Canadian David Lemieux in 2015, knocking him out in eight rounds post which he successfully defended it against the likes of Kell Brook from Great Britain and Dominic Wade from the United States of America while drawing against Canelo Alvarez.
World champion in Middleweight for the WBC, WBA and IBO Gennady Golovkin was stripped of the IBF belt for refusing to meet with Ukrainian Sergey Derevyanchenko.
Promoter Lou DiBella and Derevyanchenko then tried to get the IBF to enforce a fight between Golovkin and Derevyanchenko. The news comes after the IBF and representatives for both Golovkin and Derevyanchenko met on May 22 to discuss whether or not Golovkin could potentially move on to fighting someone else and still keep his IBF title. They were asking to have their shot at the IBF title next, but they never asked for him to be stripped.
Negotiations between Loeffler and Alvarez's handlers at Golden Boy Promotions stalled two days later because Golovkin requested more money, a 50-50 split, than he accepted in the initial deal for their rematch. Now ranking first line is Derevyanchenko, the second position is vacant, and in third place is Daniel Jacobs, which promoter Oscar De La Hoya wants to put on a fight with Alvarez Saulem. It will be Canelo making 55 percent in a rematch against GGG, which will be much bigger than the first fight was for sure.
