Following a crash late in Saturday’s Synk 275 powered by Sukup at Iowa Speedway, Arrow McLaren’s Nolan Siegel was diagnosed with a mild concussion.

The second-year driver was not cleared to race by the INDYCAR Medical Team, leading to Arrow McLaren withdrawing the No. 6 for Sunday’s Farm to Finish 275 powered by Sukup.

Siegel will be re-evaluated on Thursday prior to this weekend’s Ontario Honda Dealers Indy. Toronto.

Today, Arrow McLaren announced Linus Lundqvist as the reserve driver in the event Siegel is not cleared.

Lundqvist, the 2024 NTT INDYCAR SERIES Rookie of the Year, has not driven in 2025.

He earned a pole at Road America in 2024 and a pair of third-place finishes (Barber and WWTR).

In last year’s race on the 1.785-mile, 11-turn Exhibition Place street, he started 24th and finished 13th, one lap down in the 85-lap race.
