English driver Darren Turner has been named as a replacement for Dan Wheldon at this weekend's Armor All Gold Coast 600 V8 Supercar race in Australia.
Wheldon, who was killed in a 15-car accident during Sunday's IndyCar race in Las Vegas, was due to take part in the event at Surfers Paradise.
He was to be co-driver for V8 Supercar champion James Courtney in two 300km touring car races.
Turner, a former test driver for McLaren, will now compete in the event.
A tribute to Wheldon is planned during the weekend's events.
V8 Supercars acting chief executive officer Shane Howard said: "It was a very sad situation for everyone after Dan's death on Sunday.
"The offers of support from all levels of the international motorsport community have been amazing and it really makes you proud to be a part of this business.
"Obviously we were looking forward to having Dan, Will and Tony with us, but our thoughts are with them and their families at this time."
Wheldon was one of several IndyCar drivers due to race in Australia.
Australian Will Power, who was also hurt in the crash, has been replaced by Northern Ireland's Richard Lyons, while Brazilian Tony Kanaan has withdrawn in the wake of the accident, to be replaced by Denmark's Allan Simonsen.
Three other drivers who raced in Las Vegas - Ryan Briscoe, Alex Tagliani and Helio Castroneves - will make the trip to Australia.
