A US judge has dismissed the Las Vegas rape lawsuit against Manchester United and Portugal soccer player Cristiano Ronaldo, Britain's Sky News reported on Saturday.

Kathryn Mayorga filed a civil lawsuit in September 2018 in state court in Nevada accusing Ronaldo of raping her in a Las Vegas hotel penthouse suite in 2009, then paying her $375,000 in hush money

The ruling comes nearly three years after prosecutors said Ronaldo would face no charges in Las Vegas in connection with a 10-year-old sexual assault allegation because the case cannot be proven beyond a reasonable doubt.

Ronaldo, who plays for Premier League club Manchester United, has maintained he is innocent.

US District Judge Jennifer Dorsey kicked the case out of court on Friday over the way documents were obtained.

The judge said that dismissing a case outright with no option to file it again is a severe sanction, but that Ronaldo had been harmed by the conduct of the woman's lawyer, Leslie Mark Stovall.

"I find that the procurement and continued use of these documents was bad faith," the judge said in her ruling.

"Simply disqualifying Stovall will not cure the prejudice to Ronaldo because the misappropriated documents and their confidential contents have been woven into the very fabric of (the plaintiff's) claims.

"Harsh sanctions are merited."
