Deontay Wilder and Tyson Fury react to shock Joshua defeat on Twitter

Joshua will defend his IBF, WBA and WBO titles against Ruiz, who is looking to become the first Mexican heavyweight champion.

He had only been installed as his challenger with little over a month's notice after a suspension for Joshua's previous opponent Jarrell Miller had ruled him out, and he had also lost his only previous world title fight, in 2016 to Joseph Parker, who had since gone on to lose his undefeated record to Joshua.

He fought back in a strong way, though, and repaid the favour to Joshua. "It's a shame. But I don't want anyone to drown in their sorrows".

Not only did Ruiz come to fight, but he pulled off one of the greatest upsets in boxing history.

When asked whether he got his strength from her or his father Andy Sr, she clenched her fist and said: "I think from me!"

Very few had rank outsider Ruiz picked to beat AJ, but the signs were there. I feel this is just part of the journey I'm on.

Were these announcements made on goal to take the shine away from Anthony Joshua? Joshua knocked down Ruiz early in the round and the promise of an early finish seemed horizon.

But it didn't matter that evening as he roared back to win an all-time classic the fans will eternally admire.

Promoter Eddie Hearn said a rematch is a "must win" because Joshua's options will be "nothing after that".

I still just can't get over this dude Andy Ruiz.

Ruiz recalled the dramatic third round where he was dropped by Joshua but rebounded in ruthless fashion to deck the big Brit twice with Joshua saved by the bell to live another four rounds.

Vulnerability being laid bare in public - Joshua's up-and-down thriller against Wladimir Klitschko two years ago means this type of defeat felt possible, if not against Ruiz - is not an insurmountable problem. "Trust me, I come from a good family, but where I was at in life, I've dealt with more shit than this", he said. "This is what I've been dreaming about, this is what I've been working hard for".

The boxing world was stunned Saturday night after Andy Ruiz Jr.

Beyond that, who knows, perhaps WWE will attempt to cash in on Ruiz's sudden rise to fame and prominence by having him appear on WWE television.

Boxing Heavyweight Champion Deontay Wilder will fight lineal champion Tyson Fury in a rematch of the lip-smacking contest happened before. Ruiz is hardly expected to give any competition with odds stacked at 10-1 against him. A rematch will be a different affair because Joshua knows his career would be over if he loses. You've got to get these fights made in a timely fashion.

"It was an incredible night of boxing at the Garden, I'm sure everyone will remember it forever", Hearn said. "We just made history".

The exchange according to dailymail.co.uk was caught on camera in the background as Ruiz was being interviewed in the ring following his unexpected seventh-round win.
