Rod Findlay has stepped down as Crusaders chief executive following the club's withdrawal from Super League.
The Rugby Football League's former lawyer joined the financially troubled Welsh franchise in December 2010.
"It is a great regret that the owners decided to withdraw the Super League application," said Findlay.
"Because we were building something really good on and off the pitch and north Wales is an area that has taken rugby league to its heart.
"There is a lot of local support and some prominent local people pushing for a club under new ownership in 2012.
"This needs to be locally led with everyone getting behind a sustainable club.
"I have offered support and advice to those involved but now is the time for both me and the club to look to the future."
The Crusaders' application to play in the 2012 Championship is still being assessed by the RFL but Findlay confirmed he would not be part of the new club.
Coach Iestyn Harris and the bulk of the players have also left the club following their final Super League match, the 42-10 defeat at Wigan last Friday.
