Lance Stroll will take the start of the Mexico City Grand Prix from the pit lane, the FIA has confirmed.
It marks the second consecutive race that Stroll will line up in the pit lane for the commencement of the Grand Prix.
Stroll ended Saturday's qualifying session in 18th, his sixth Q1 elimination in a row, but he was set to start one position higher due to a grid penalty for AlphaTauri's Yuki Tsunoda.
However, Aston Martin opted to change a number of components overnight which breached parc fermé conditions.
The changed parts include the floor, sidepod, rear beam wing and rear anti-roll bar - all of which are a different specification to Saturday's version.
As a result, Stroll will has been removed from the starting grid and placed in the pit lane, as he was one week ago at the Circuit of the Americas.
Aston Martin's decision to start Stroll from the pit lane in the USA worked in its favour, as the set up changes helped the 25-year-old to rise to seventh place at the chequered flag.
