Max Verstappen sits out for Red Bull in Mexico GP FP1

Max Verstappen will step aside during first practice at the Mexico City Grand Prix as Red Bull continues to complete its quota of rookie runs in FP1 sessions.

Teams are required to give rookies - designated as drivers to have raced in two or fewer races - at least four opportunities to run during practice sessions across the season, with that quota split between two watching briefs per race-contracted driver.

Four-time world champion Verstappen will be replaced at the Autodromo Hermanos Rodriguez by Ayumu Iwasa, who has already made three FP1 appearances this term.

The Japanese driver drove the RB22 at the Circuit de Barcelona-Catalunya and Monza, while he stepped into the Racing Bulls car in Austria.

It will mark Iwasa's eighth FP1 outing in total, with this being his second run in Mexico following his appearance for Racing Bulls last year.

Verstappen and Red Bull have enjoyed a resurgence of late, securing wins at Sepang and Singapore before picking up another podium at last weekend's United States Grand Prix.

But that hasn't meant that the Milton Keynes-based squad has found answers to all of its problems, with poor race starts and radio issues continuing to plague the Dutchman and team-mate Isack Hadjar.

Iwasa's involvement follows on from a spate of announcements regarding rookies running in FP1 in Mexico.
