The Frenchman still does not have permission from the IndyCar Medical Team to compete after suffering concussion-like symptoms, with the 2022 Indy NXT series winner to again steer the #60 Honda this weekend at The Brickyard.
It comes after Lundqvist qualified 11th in Nashville and was running 13th when he crashed on Lap 70.
“First, I want to say a massive thank you to Mike [Shank] and Jim [Meyer] for their trust to put me back in the car again,” said the 24-year-old.
“The Nashville weekend was great in so many ways. Obviously, a lot of impressions and a lot of new stuff for me going on that weekend and I was pretty disappointed with the way that it ended.
“It was my mistake and I enjoyed it up until that point. I think it also left me and the team wanting more, which I am grateful for another opportunity at Indy.
“I know it is going to be tough again, but now I have a whole race weekend under my belt.
“Hopefully we can string some good results together and find some good speed, but I feel like it is going to be a super weekend.”
Practice starts on Friday at 09:00 ET/23:00 AEST and can be seen live and ad-free in Australia on Stan Sport.
Qualifying and Final Practice follow later on Friday before racing on Saturday, as part of a double-header weekend with NASCAR.
