VIDEO: How Ruiz Jr stunned Anthony Joshua to claim WBA, WBO and IBF belts

Andy Ruiz Jr sprung one of the biggest shocks in heavyweight championship history on Saturday night when he spoiled Anthony Joshua’s US debut with a seventh-round technical knockout at Madison Square Garden.

The unheralded 29-year-old from southern California, a replacement opponent dialled in on five weeks’ notice who went off as a 11-1 underdog, came off the floor in the third round to drop Joshua twice before the end of the frame, then sent the undefeated champion crashing to the canvas for a third and fourth time in the seventh round before referee Mike Griffin put a stop to the proceedings at the 1:27 mark.
