A social media video of star Gold Coast Titans recruit Jarryd Hayne with an alleged bikie, who is holding up $5,000 cash he says Hayne gave to him, has been passed on to the NRL's Integrity Unit.

The video, posted on Snapchat, showed Hayne with alleged Hells Angels bikie Chris Bloomfield on Saturday night, a day after the Titans lost an elimination final to the Brisbane Broncos.

Former Titans winger Nene Macdonald also briefly appeared in the video.

The post showed Bloomfield holding $5,000 in cash which he said Hayne gave to him.

But Bloomfield's lawyer Adam McGill has told the ABC Bloomfield was a former professional rugby league player and had become friends with Hayne through football.

He said the pair were just catching up and had not seen each other for a long time because Hayne had been playing overseas.

'It's very, very innocent'

Mr McGill said the money in the video did not show anything illegal being carried out.

"That's just the boys being the boys and a bit of tomfoolery," he said.

"I think it was a bit of showboating on Chris's behalf, but there was certainly nothing illegal or sinister in relation to the money, they were just showboating.

"At that stage they had all been drinking and like a lot of Australian males they tend to put on a bit of a show.

"Obviously it was Jarryd's money, Chris got it and he was just making light-hearted comments in relation to 'this is what he gave me'.

"He never gave him the money, he just gave it straight back to him."

Mr McGill said it was only an issue because Bloomfield was a member of an outlaw club.

"Just speaking to my client this morning, he still doesn't understand the circumstances or why everybody is making such a big deal out of the whole situation," Mr McGill said.

"It's very, very innocent."

Former NRL player and leading sports lawyer Tim Fuller said Hayne could be punished over his association with an alleged outlaw bikie.

"Ultimately what the NRL will do after they investigate along with the Titans of course ... will look at it and decide whether he has basically brought himself, the sport, or the club, into disrepute," he said.

The Titans are liaising with the NRL's Integrity Unit and the players over the matter.

They said they would speak with Hayne before commenting further.

The ABC has contacted the NRL for comment.
