Manly have announced CEO Lyall Gorman will end his tenure in the role to lead the club's Centre of Excellence.
Gorman, who has been the Sea Eagles boss since November 2017, will make the transition to overseeing the development of their training base after the club secured $32.5 million from state and federal government grants for the Centre of Excellence at Lottoland.
Gary Wolman, a Sea Eagles director and part owner will assume the role of interim CEO until a full-time replacement is found.
"We're excited to have someone with Lyall's experience lead what is one of the most important projects and financial commitments in our club's history," Sea Eagles chairman Scott Penn said.
"The Centre of Excellence will deliver state-of-the-art training, administration, community and multi-purpose facilities that will ensure the Sea Eagles can compete at the highest level and it is vital that the project is delivered on time and on budget. Lyall is perfectly positioned to deliver our goals."
"On behalf of myself, my fellow board members, our members and fans, I would like to thank Lyall for his contribution, guidance and leadership as CEO over the past 18 months.
"We look forward to this next exciting chapter as we continue on our journey to become a benchmark club across sport in Australia."
Gorman said in the club statement that he was looking forward to the Centre of Excellence project.
"It has been a privilege and a pleasure to be the CEO of this great club and I will continue to do everything I can to work with both board and management to deliver this vital piece of infrastructure,'' he said.
"The achievement of our property and stadia related goals will be a major driver of our future sustainability as a club. I am incredibly excited and committed to bringing this next chapter of our club's rich history to life."
