What happened: Liam Lawson was disqualified from Mexico City Grand Prix qualifying following a technical infringement discovered after the session. Technical inspectors identified an engine-related irregularity that invalidated his qualifying times. As a result, the stewards ruled that he must surrender his grid position.

Why it matters: The exclusion compounds a turbulent weekend for Lawson, who was previously penalized after a Mexico GP practice clash during Friday sessions. Starting from the rear severely complicates his strategy at the Autodromo Hermanos Rodriguez, where high altitude and turbulent air make overtaking difficult.

What to watch: Lawson will line up at the back of the pack when the Mexico City Grand Prix gets underway on Sunday.
