The former Western Sydney Wanderers CEO and previous head of the A-League joined the Sharks in 2014.

He helped turn the club from Wooden Spoon winners to NRL Premiership winners.

Gorman is expected to move to fellow NRL club Manly for next year.

“The Club wishes Lyall well in his future endeavours and thanks him for his service and the outstanding contribution he has made to our business over the past three years," said Sharks Chairman Mr Dino Mezzatesta.

“As Lyall said upon arrival at the Sharks and as was also included in his departure announcement to staff, ‘If you think that our future is all about me we are in deep trouble, but together we can and will create something very special’.

“Lyall played a big part in our premiership success of 2016 and leaves the Sharks in an extremely healthy position both on and off the field and we are confident we can build on the work he has done and make our Club even bigger, better and more successful going forward."
