In his Twitter account, UFC veteran Nate Diaz (0-1, 0 KOs) declared his readiness to face the top contenders of the heavyweight division (over 90.7 kg).
"Anthony Joshua, Deontay Wilder, Tyson Fury – I'll beat your asses. Just so you know," Diaz wrote.
Diaz has previously threatened Fury and Joshua, stating that he would "smash them in a real fight."
Last August, Nate Diaz made his professional boxing debut against Jake Paul (9-1, 6 KOs) and lost by unanimous decision of the judges.
