Police say Nelson Thomas was knocked out cold after chatting up a married woman in Las Vegas.
Nelson, who has starred on "The Challenge" for years, told the police that he met a woman at ARIA Resort & Casino and started talking to her at the valet area. WHAM! Nelson was awakened by someone telling him that he had just been punched in the face and had his chain stolen.
Nelson was punched in the head by a woman who then hit him one more time.
Nelson says he was sucker-punched and left with a broken nose, which made him unable to get a doctor to treat him.
Nelson claimed on social media that he was attacked because someone was trying to steal his $10,000 chain, but the woman's husband, Kevin, told a different story.
According to the police report, Nelson was talking to his wife in an elevator when he walked off, but his wife stayed on and kept talking with him.
He lost sight of her and was trying to text and call her when he found her talking to Nelson. Cops say he admitted to being drunk and jealous in Vegas.
He was arrested for battery and grand theft.
Nelson is on the mend, and it looks like his nose is fixed after treatment.
