An oversight by Norwegian publishers Gyldendal meant that the episode -- which sees Eriksson chased from the house without his jacket, wallet, phone or shoes -- was there for all Norwegian readers, leaving the saucy Swede red-faced.
The story began with a night out on the town with Glenn Schiller, a former player for IFK Gothenburg, which ended in the apartment of one of Schiller's female friends.
"We soon found ourselves naked on the sofa," Eriksson writes in his matter-of-fact style. "She had not said anything about being married but suddenly the door opened and there was a big man: 'Who the hell are you?' he said. I said: 'I think it is probably best if I leave,' and he replied: 'I think it probably is.'"
Luckily for Eriksson, he found a pair of basketball shoes, size 46, outside the flat, which he stole to make his getaway.
"I normally, like Maradona, wear shoes the size of 39 but what choice did I have? I had to borrow them," Eriksson writes. "What would have happened if a photographer had seen me, walking around in just a shirt with basketball shoes seven sizes too big? That would probably have created a few headlines."
Eriksson refused to comment in a press conference in Stockholm on Thursday to publicise the book.
But Jan Swensson, Gyldendal's editor-in-chief for non-fiction, described the mistake in the Norwegian edition of 'Svennis', as "embarrassing".
"It's a mistake and it's completely our fault," he told The Local. "Norstedts were editing all summer, taking things out and putting things in, and somehow we didn't manage to take out this piece. The reason is that the manuscript wasn't finished while the translator was working."

He said that Gyldendal had only printed 4,000 copies with the additional juicy story, and would cut it from all future editions.
"Hopefully there will be a print run before Christmas, and we'll sort it out," he said. " I think it will probably be on the bestsellers list and a nice christmas present for football fans in Norway. It will be a big seller."
