"In saying all of this I would like to apologise to Kyle Feldt, to the NRL and to the gay community, and anyone else that I have offended, as I know and respect the work that the NRL has done to ensure inclusiveness and diversity within the NRL community.
"Moving forward I can only assure you that I have learned from this lesson and this will never happen again."
NRL.com reports NRL legal counsel Lachlan Gyles told the panel Montoya should be suspended for six matches for the offence but sought a four match ban due to his previous good record, the remorse he had shown and his guilty plea.
George, who also appeared in the hearing via video link from Auckland, said the club would offer Montoya all the support he needed.
"We know how disappointed Marcelo is with himself. He's devastated and we really feel for him and what he has been going through," he said.
"As a club we don't condone such behaviour in any circumstances and nor does Marcelo. He will learn from this and will use it to move forward from this episode and be the best person he can be. We'll offer him all the support he needs."
While the side will be without Montoya until round 10, they will welcome back veteran Dallin Watene-Zelezniak in his place on the wing for this Sunday's match against the Sydney Roosters at the Sydney Cricket Ground.
