Rugby star Mitchell Pearce was allegedly caught on film simulating a lewd act with a dog.

Rugby league star Mitchell Pearce has reportedly been filmed simulating a lewd act on a dog in what has been labelled a potentially career-ending scandal.

The Sydney Roosters premiership captain allegedly made advances towards a woman, who rejected him, and then urinated on himself at an Australia Day house party, Yahoo7 reports.

The video, which was reportedly offered to various media organisations and aired on on A Current Affair tonight, shows the 26-year-old picking up a small dog and simulating a lewd sex act on the animal.

In the video, Pearce says: “I’ll **** that dog, I don’t give a ****. I don’t have a sexuality… I don’t have a sexuality.”

A woman tells the Origin player the dog is off limits and asks him to stop.

She then takes the dog off him and tells Pearce – who she questions about urinating on her couch – to get out of her house.

The rugby team had been on a Sydney Harbour boat cruise earlier that day.

The alleged incident has been likened to Cronulla Shark Tod Carney’s career-ending ‘bubbler’ incident in 2014, where he was photographed urinating into his own mouth.

The Roosters have said they are aware of the incident and have referred it to the NRL’s Integrity Unit.
