Baird, who is signed on to partner David Reynolds in the #9 entry at the enduros this year, was scheduled to drive the car during Friday’s co-driver session.

However his last-minute appointment as the main driver of the #4 Erebus car, following Aaren Russell’s departure from the team, means Baird won’t be available for 30-minute session on Friday afternoon.

As a result, Douglas has been nominated by the team as the driver of the Reynolds car for the co-driver session.

Douglas, who races in both the second-tier Dunlop Series and third-tier Kumho Series, is currently without a drive for the endurance rounds, although is expected to be in the frame for a touted Wildcard entry from Eggleston Motorsport.

Erebus, meanwhile, is yet to reveal its longer term plans following Russell’s departure, with Baird’s current deal a one-off for the Ipswich weekend. Should he continue to race the #4 for the remainder of the season, Erebus would need to find a replacement co-driver for Reynolds ahead of Sandown, Bathurst, and the Gold Coast.

Douglas declined to comment on the Erebus situation when contacted by Motorsport.com, confirming only that he’ll be at Queensland Raceway this weekend for the Kumho Series round.
