Lucas Dumbrell Motorsport is searching for a driver for this weekend’s Watpac Townsville 400 after Cameron McConville elected to vacate his seat at the team.

The veteran was set to pilot the #3 Commodore at Townsville as part of a deal that saw him contest the last Supercars round at Darwin’s Hidden Valley Raceway last month.

However, the 43-year-old informed the team’s backer Phil Munday on Sunday that he is no longer able to commit to the drive due to an increasing workload in his role as team manger at Zagame Motorsport.

McConville oversees programs in Australian GT, Porsche Carrera Cup, GT3 Cup Challenge and Formula 4 at the Melbourne team.

“There is no hidden reason other than I juggled it at Darwin, and I enjoyed it, but I looked ahead at the next couple rounds and I can’t do it justice with the amount of time it requires to do it properly,” McConville told Speedcafe.com.

“I spoke to Phil Munday on Sunday and I didn’t want to pull the pin last minute but my workload at Zagame Motorsport is too much.

“It is not fair to my employer so I need to focus on Zagame and continue to grow that business.

“I did enjoy Darwin and I would love to be at Townsville but it is just not fair to Zagame.

McConville told Speedcafe.com that he had been set to continue his duties with the team after Townsville before reassessing his current situation.

The former Supercars full-timer believes his drive at Hidden Valley will be his last in the category.

The decision leaves LDM searching for a last minute replacement with the squad currently assessing a shortlist of drivers.

Dumbrell confirmed to Speedcafe.com that an announcement is expected later today.

Taz Douglas has previously driven for the team on a round-by-round basis, while Matthew Brabham filled in at Perth in May.

Speedcafe.com understands that the American-based Brabham is not being considered as a stand in for this weekend.

Nissan Motosport co-driver Dean Fiore and former full-time Supercars driver Alex Davison are thought to be among the contenders.

“Cameron was overwhelmed with the amount of work he has got on as he is running a race team in four or five different categories,” Dumbrell told Speedcafe.com.

“Racing in the main game is not a part-time thing.”

Regulations dictate that the team must find a driver who is eligible for a Superlicence and not competing in this weekend’s Dunlop Super2 Series round.
