Meanwhile, the club have announced the re-signing of both Jones and Iro through to the end of the 2020 season.
Jones was appointed an assistant coach when head coach Stephen Kearney joined the Warriors following the 2016 season, while Iro rejoined the NRL football staff this year after previously filling the assistant coach's role with Ivan Cleary, Brian McClennan and Andrew McFadden.
"Stacey and Tony have done a wonderful job in their roles and in challenging the group to constantly improve," said Kearney.
"They bring tremendous experience with their playing backgrounds and are constantly looking to develop as coaches.
"From a club viewpoint it's also really important that we have some continuity with our football staff so it's terrific that we've been able to keep Stacey and Tony onboard."
