Liam Lawson is set to miss first practice at this weekend's Austrian Grand Prix, with Racing Bulls opting to field a rookie.
Red Bull junior driver Ayumu Iwasa will replace Lawson for first practice at the Red Bull Ring, marking his second outing of 2026.
His first came at the Spanish Grand Prix, where he drove Isack Hadjar's RB22 for the main Red Bull outfit.
It represents the first of two FP1 sessions Lawson will miss in 2026, with each team required to field a rookie in four first practice sessions, twice in each car.
This is a mandatory rule in F1, but with Arvid Lindblad being a rookie, his first two FP1 sessions counted towards Racing Bulls' overall total.
