NRL players trialling for NFL franchises might quickly become a thing of the past.
Club bosses are keen to put a clause in the standard NRL player contract that prevents such actions and NRL CEO Todd Greenberg has backed them after the CEOs conference on Wednesday.
"The clubs have made it clear that they don't want their players going to another code, including NFL, and risking serious injury," Greenberg told News Corp Australia.
"That is a view the NRL shares, we don't support players going off to play with or promote other codes.
"They are contracted to play with the NRL and we do not believe they should try their hand at another code and expect to come back to rugby league if it doesn't work out."
