Bulldogs officials questioned Napa on Friday about the video, which has gone viral on social media.

It is understood the film was taken around four years ago when Napa was still at the Sydney Roosters.

The video shows a much younger Napa, with a fuller head of red hair, less bulk and no tattoos on the backs of his legs. The vision is filmed from a nearby bed.
