Mark Harvey has quit the Lions.
Mark Harvey has quit the Brisbane Lions' coaching staff amid speculation the former Bomber is a strong candidate along with Mark Thompson for the role at Windy Hill.
The Lions announced Harvey's departure on Thursday after two seasons as assistant to then-senior coach Michael Voss.
New Lions' coach Justin Leppitsch's support team will include former Hawthorn coach Peter Schwab as head of coaching and development.
Schwab, the AFL's director of coaching, will oversee management of coaching staff in the football department.
The ex-Hawk starts in November and will also provide support to 37-year-old rookie coach Leppitsch, a former assistant at Brisbane and Richmond.
"Harvey advised the club earlier this week that he would be seeking opportunities elsewhere in 2014," the Lions said in a statement.
Ex-Fremantle senior coach Harvey is a triple-premiership player at Essendon. Senior coach James Hird's 12-month suspension over the the Bombers' use of supplements leaves Essendon seeking to make a short-term appointment.
Harvey and 2013 Essendon assistant coach Thompson are considered among the frontrunners.
Former Bombers skipper Thompson, a two-time premiership coach at Geelong before returning to Windy Hill as Hird's right-hand man in late 2010, stated this week he'd do the job if the club wanted him.
Harvey was a senior assistant and football strategist at Brisbane and was caretaker coach for the last three games, replacing Voss.
The 48-year-old Harvey played in three premiership sides at Essendon and was an assistant to Kevin Sheedy for eight years.
Brisbane assistant coach Adrian Fletcher is also leaving the Lions after six seasons of service, the Lions said.
"Mark and Adrian have been valuable members of our off-field team and we thank them for their contribution over the years," Brisbane football operations manager Dean Warren said.
Schwab said he was thrilled to be returning to club football.
"I've always had a desire at some point to get back in the AFL system and felt this was a great opportunity with a new coach and good young team," he said.
Former Collingwood forwards' development coach Mitch Hahn has been given a development role on the Lions' coaching staff.
