Greenberg’s statements come after the Sharks premiership winner signed with French rugby club Toulon overnight.

“Ben does not have a registered contract with the NRL so he is free to make a decision to play in a different code with a new club,” Greenberg said.

“But the NRL will not consider any contract for registration until he has completed his contract with other sports.

“The match suspension he needs to serve will only begin after he has completed his playing commitments elsewhere.”

The NRL is yet to register Barba’s new Sharks deal.

He has not had an income since his release from Cronulla in October following a positive drugs test.

He has four children and mortgages across three properties.

“We have been working closely with the Sharks on ensuring he has access to appropriate courses and programs as part of his rehabilitation,” Greenberg said.

“We have just given him approval to train individually at the club and be part of the Shark's community programs.

“That agreement meant he also had access to the club’s welfare and education support services.

“If that commitment has changed then it will be taken into account when we consider whether his contract should be registered.

“I would hope that everyone involved in this matter is looking at how we look after Ben’s welfare first and foremost – and football matters should be secondary.”
