Boxing chiefs in California have suspended Bulgarian heavyweight Kubrat Pulev's licence after he "forcibly" kissed a female reporter Jennifer Ravalo on the lips during an interview.
Pulev claimed the pair were friends, but Ravalo said she had only met the boxer a day earlier.
Ravalo's lawyer Gloria Allred said his actions were "unwelcome and unlawful".
The heavyweight has been ordered to appear in front of the California State Athletic Commission.
Ravalo said that what Pulev did was "disgusting" and left her "humiliated".
"Mid-interview he grabbed my face and kissed me. I was immediately shocked and embarrassed, and didn't know how to respond. Next, I walked to the table to put my items in my backpack. He grabbed both of my buttocks and squeezed with both of his hands. Then he walked away without saying anything to me and laughed. It made me feel uncomfortable and frustrated that Kubrat Pulev would treat me in such an unprofessional manner. I did not encourage or consent to Mr Pulev grabbing my face, kissing me, or grabbing my backside. I was there at the event covering the boxing match as a professional member of the press. Kissing a woman on her lips without her consent and grabbing her is not acceptable. No woman should be treated this way."
