Ford Performance Racing (FPR) has drafted in experienced international driver Richard Lyons to replace Will Power alongside Mark Winterbottom for this weekend's Armor All Gold Coast 600 following an accident at the IndyCar finale at Las Vegas.
Power, who was not seriously injured in the multi-car accident, will not take part in the GC 600 as a consequence of the crash.
Singapore-based Northern Irishman Lyons is well-credentialed having won both the Formula Nippon and Super GT titles in Japan during his career.
FPR Team Principal Tim Edwards thanked Lyons for accepting the role in such difficult circumstances.
"On behalf of everyone at Ford Performance Racing I would like to pass on our heartfelt condolences to the family and friends of Dan Wheldon," Edwards said.
"It was a terrible accident and our thoughts are with them.
"Our thoughts are also with Will Power at this tough time and we are just thankful he has escaped without any serious injury.
"I'd also like to thank Richard Lyons for stepping in at such short notice in place of Will. I have known him since my Formula 1 days and he has always impressed me so I am sure he will adapt quickly to our car and the Surfers Paradise track."
Lyons will shortly be on a plane to Australia and was glad he could assist the team at such short notice.
"I am really torn about racing as I literally heard the sad news about Dan's passing only an hour before I spoke with Tim," Lyons said.
"I've known Dan for about 15 years as we started off racing together as juniors. We lived nearby in England and we hung out whenever we could so it is with a heavy heart I come to Surfers Paradise.
"While I am sorry that Will can't come I look forward to working with such a seasoned professional as Mark Winterbottom and it is a great opportunity for me to work with FPR.
"I've known Tim for many years and I've wanted to drive for him since he worked for Jordan back when he was in Formula 1. So I am grateful that he has called me and I am looking forward to the challenge of another new car and circuit."
