In a truly remarkable fight at New York's Madison Square Garden, Ruiz floored Joshua four times en route to a seventh-round stoppage which stunned this famous arena and handed the Briton his first defeat as a professional.
Joshua was a 1-25 favourite with bookmakers and will now join the likes of Lennox Lewis and Mike Tyson as dominant champions to suffer losses which brought the sport to a standstill.
"I got beaten by a good fighter," said Joshua on Sky Sports. "It will be interesting to see how far he goes, but this is all part of the journey.
"He's a champion for now, I shall return."

Callum Smith was punch perfect, Katie Taylor was involved in the best women's fight I have seen, even if the result wasn't right, and Andy Ruiz's shock victory completed a great night of boxing.

Earlier this year, rapper Drake was "banned" from speaking to football players or teams on as every time he was pictured with them they then lost.
He met Joshua earlier this year, who then posted a social media message saying he was 'bout to break the curse'.
Don't think Drake's going to be allowed near any athlete again soon.

That ends any doubts of whether Joshua would walk away from boxing after this stunning defeat.
Anthony Joshua, talking at a news conference after his shock loss to Andy Ruiz, says: "I’ll see what is next and move on. He is a decent fighter and it was his chance, it can be easy to overlook someone because of their shape but he was the better man tonight and he won.
"If people ask me about Deontay Wilder and Tyson Fury, I’m all ears to it and I’ll give you the answer. I still want to compete with those men but a rematch with Andy Ruiz Jr is where we are at. I got caught on the top of the head and I just didn’t recover in time, so now I brush off the cobwebs and go again."
Asked how much a setback it was in his career, he said: "Naturally it does, but if it was the end of the road I would say yes, but it’s about what is next. It is a minor setback but the locks on the door do not change and I still love the sport.
"I’m still a champ and I will rectify it to get the belts back. I come from a good family but I have dealt with more than this in life. I feel it is part of a journey I am on, and this is boxing. We didn’t come this far to stop under pressure."
"A minor setback" is the way Anthony Joshua is trying to downplay this.

Joshua is having a concussion test.
Word was he wasn't doing a news conference due to doctor's view. Eddie Hearn now saying he is going to find out for sure.
#bbcboxing
Riquelme: AJ's bizarre post fight behaviour (all smiles etc) is because his personality was media trained all along, and he obviously hadn't media trained for losing. He is all manufacture.
ShoG0n: He's an embarrassment to British boxing, Ruiz outclassed him. He was pampered from the word go, he should hang his head in shame

"I want to go and get in shape and look like the Mexican Anthony".
The words of Andy Ruiz Jr, who earns himself a big laugh.
He adds: "Follow your dreams, if someone puts you down don't listen, just keep working like I did. We just made history.
"The way that I look. The extra flab I carry. I didn't want to lose much weight for this fight, I wanted to be strong as he's a big guy. Now I want to get in real good shape and look like a Mexican Anthony."
Just waking up? This is what you are waking up to. One of the biggest shocks in boxing history and this is how it unfolded...
Two of the three ringside judges had Anthony Joshua losing by 57-56 when the fight was stopped in the seventh. The other judge had the score that way in Joshua's favour.

Andy Ruiz is doing his news conference and says he would have knocked Joshua out had the fight continued, thinks this will change his life and his mother will not have to "struggle" anymore.
"This is not going to be the only victory. I am not going to let these belts go," said Ruiz.
Anthony Joshua's promoter Eddie Hearn says this result has "not sunk in" and said that Joshua is getting checked by the doctor but is OK.
"This will eat him up bad," added Hearn. "Some fighters lose and fight back, some never come back the same."
