Deontay Wilder has slammed "miserable" Chael Sonnen after his criticism of his two-fight call-out to Francis Ngannou.
Boxing star Wilder has recently returned to the heavyweight division where he poleaxed Robert Helenius in the first round of his first fight since losing his trilogy fight to Tyson Fury. However his future is uncertain since declaring he is a free agent, having seemed certain to face stablemate Andy Ruiz Jr in a WBC world title eliminator.
The 'Bronze Bomber' has since issued a call-out of former UFC heavyweight Ngannou, who he has claimed he would be open to doing battle in both the cage and the boxing ring. But former MMA star Sonnen was left unimpressed by the deal and blasted the star as a "coward" on a recent YouTube video.
