Star Canterbury recruit Dylan Napa faces missing the start of the season, with NRL chief executive Todd Greenberg rebuking him for bringing the game into disrepute.
The NRL integrity unit is finalising its report into a series of lewd videos featuring the Queensland Origin prop contributed to the game's summer from hell after they were uploaded to the internet.
Over the last several days ugly rumours have circulated that Napa was the subject of another video along with a former teammate.
However, the NRL said they had viewed that vision and cleared both players.
Greenberg would not speculate on a possible punishment and said he wanted the matter finalised as quickly as possible.
"I haven't read (the report) in its entirety but what I have read is damage to the game," he said.
"Where damage to the game comes, there will be consequences."
Any suspension would be a cruel blow for the Bulldogs as the videos were filmed several years ago while Napa was playing for the Sydney Roosters, and he was not involved in making them public.
But the videos form one of the most damaging sagas in a disastrous off-season labelled a "train wreck" by Greenberg.
Greenberg's disappointment was evident on Tuesday as Napa's former teammate Kane Evans, who is featured in one of the three videos, sprang to the forward's defence.
In one video, Evans is seen shadow boxing in the background while Napa performs a sexual act on himself.
And the Parramatta prop said if he had his time over he would not have agreed to take part.
"A hundred per cent, definitely wouldn't have made it," Evans told AAP.
"If we knew it was going to get leaked, no one would make those videos.
"After these recent videos, I'll definitely be thinking differently.
"Just be more cautious, even when I'm in my own home, about what I say and do because we're all role models and people are looking up to us.
"I've got to be on my best behaviour."
Despite conceding the videos were a mistake, Evans said people were too quick to pass judgement on Napa.
"He's got a good heart, he's a good bloke," Evans said.
"He's one of the funniest guys to have around, I love him.
"People are judging him but who are they? No one is perfect. People can't be throwing stones from a glass house."
