A remorseful Josh Dugan says he is on his last chance as the troubled star begins the second phase of his NRL career with St George Illawarra.

After much speculation, Dugan finally signed with the Dragons on Friday for the rest of the season after being sacked by Canberra in March following a series of disciplinary breaches.

Dragons coach Steve Price indicated Dugan could be a late inclusion in his side to play Gold Coast at Skilled Stadium on Sunday and the former NSW custodian was relieved to have been given another chance.

"I have had 10 weeks to think about it and I'm very remorseful about how things went down," Dugan said.

"I made my debut with Canberra and I earned my rep jerseys with Canberra so I'm grateful for the opportunity they gave me and I'm also grateful for the opportunity the Dragons have given me.

"I had a couple of stuff-ups at Canberra, that has been well documented, and I think this is the last chance I will have.

"Hopefully I can earn a long-term contract with the Dragons.

"I thought my career might be over and ... there is nothing else I want to do other than play rugby league. I have had a lot of time to think about how things went down and I probably could have done things a little better."

Dugan admitted to a falling out with Raiders coach David Furner but said a picture of him gesticulating rudely posted on a social media site was not aimed at his former mentor.

"We had words but it was never as bad as everyone made out," Dugan said.

"I messaged him the next day and apologised for the way things went down and thanked him for the opportunity."

Dugan said he had undergone counselling sessions as part of the NRL allowing him to return to the game and would continue to do so.

He said was under a self-imposed booze ban of "at least six weeks".

Dugan added he would continue to use social media despite its pitfalls that had cost him a contract with Brisbane as he remained keen to interact with fans.

"For every 10 people who get stuck into me, there are 100 who stick up for me," he said.

Dugan's signing is a massive boost for the Dragons' sputtering attack and Price said he would decide on Saturday whether to bring him in against the Titans.

"I'm not writing it off," Price said.

"I just have to get a gauge on where Josh is at. He is in a really good head space. He has been training behind the scenes on his own.

"I'll have a look at him tomorrow and make a decision then."

Price doesn't believe the Dragons were taking a risk signing Dugan.

"He is a real talent and of all the discussions and all the meetings I have had with Josh he is a 10 out of 10 bloke. Everybody makes mistakes and Josh made one of those and he deserves a second chance," Price said.
