ANDY RUIZ JR admitted he let fame and fortune go to his head – and his belly – after beating Anthony Joshua in June.

Fury has since returned to boxing, playing out a controversial draw with Deontay Wilder.
He will step back into the ring for his highly-anticipated rematch against the Bronze Bomber this weekend in Las Vegas.
