Josh Dugan in action for the Raiders against the Panthers in round one.
The Brisbane Broncos have ceased negotiations with former Canberra star Josh Dugan after the troubled fullback was involved in another social media spat in which he suggested a Raiders supporter should "end themselves".
Dugan was sacked by the Raiders earlier this month for repeated code of conduct breaches that peaked with the 22-year-old posting a picture of himself on photo-sharing website Instagram, drinking on a rooftop and giving the finger to the camera.
Instagram was again his medium of choice on Saturday night when Dugan angrily responded to taunts from Raiders fans who remain upset about his exit from the club.
The gifted fullback unleashed a verbal tirade that included an invitation for a face-to-face confrontation with one of his antagonists.
Dugan was reportedly close to signing a deal with the Broncos but after the latest social media imbroglio the club issued a statement on Sunday afternoon saying they had pulled out of talks with his manager Paul Sutton.
"We will not be making any attempt to register a contract for Josh Dugan with the NRL," said Broncos chief executive Paul White.
"While there were some negotiations, they are now over.
"In light of some fresh allegations of inappropriate behaviour, the Broncos have decided not to take the matter any further."
Responding to one user who suggested the Raiders were better off now because the replacement fullback, Reece Robinson, was doing a good job, Dugan launched an profanity-laden rant (with expletives removed below).
"I'd hate to be ya nuffie," Dugan said.
"At least my dog doesn't speak up like you ya loud mouth ... who are ya by the way? I could never play another game of NRL and I've still accomplished more than you.
"Haha righto Marky Mark: go get another Raiders Tattoo then end yourself.
"Your mrs is hot too by the way haha you obviously don't read the news more the fool you haha your a joke.
"All my tats put together are better than your one rubbish one plus your bad head.
"Should call you don bradman ya batting well above average with her.
"Send her my way ill show her the time of her life."
On Sunday the one-time NSW State of Origin representative attempted to calm the situation by posting an apology.
"(There are) 2 sides to every story and only the bad side of my story has been told over the last few weeks," Dugan wrote.
"Yes I stuffed up and yes I'm paying my price. But people go on and on about bullying when I am constantly being harassed for simply putting a photo up.
"I apologize (sic) to those who I had bad words with but I am a normal person like anyone else.
"Media can write what they want but (they) have not spoken to me personally or seen the abuse I have copped.
"Life goes on and I'm trying to move forward with my life and career."
However the apology didn't hit the mark with his main antagonist, who sent another vile message.
That prompted Dugan to suggest a meet up to sort out their problems in person.
"I was actually going to apologize to you but now there's no point," Dugan said.
"I'll be in Canberra next weekend if you want words."
