Former Cronulla coach Shane Flanagan is tipped to fill the final vacancy on St George Illawarra's new-look support staff after the NRL club completed an end-of-season review.
Paul McGregor will retain the head coaching reins but his off-field staff have received a shake up under the sweeping review led by Phil Gould after the Dragons' 15th placing in 2019.
Former Newcastle assistant James Shepherd will become one of McGregor's new deputies, with Ben Hornby and Mick Crawley off-season departures from Kogarah.
The Dragons said they had one spot left on their support staff roster and would make an announcement at a later date.
Former Sharks premiership winning mentor Flanagan is expected to be officially unveiled as a Dragons assistant next month when his NRL ban expires.
Flanagan was suspended indefinitely in December last year after he was found to have broken the terms of his 2014 supplements scandal ban by communicating with Cronulla officials.
But the NRL announced in September that Flanagan would be eligible for registration as an assistant for the 2020 and 2021 seasons.
"Everyone at the Dragons were terribly dissatisfied with the club's 2019 season campaign which resulted in this wide-ranging internal and external review of the club's football department," Dragons CEO Brian Johnston said in a statement.
"The Dragons have made key structural changes to its coaching, performance and medical staff following the determination of a lack of experience within the wider group.
"This includes several new staff appointments to the football department.
"It was noted throughout the review that there needed to be a greater focus on club culture and leadership.
"In acknowledging this, the club have taken steps in this space in order to bring further accountability and discipline to the playing group."
Among other changes, Adrian Jimenez replaces Alex Clarke as strength and conditioning coach and Steve Dean will head the physio department also featuring Davis Theobald (rehab) and NSW Origin head physio Dan Lawson (part-time).
Gerard Murphy - who has worked with AFL clubs, the England rugby and league national outfits and British Olympic team - will help guide "culture and leadership space".
The Dragons have also hired mind and performance coach Matt Griggs, a former professional surfer who will hold meditation lessons "among other things".
