Oscar Piastri's British Grand Prix on Sunday was ruined by an opening-lap collision with Liam Lawson's Racing Bulls car.
What happened?
The Australian driver, who started eighth on the grid, sustained damage to his front wing on the run towards Turn 6.
He immediately reported the damage to his team, saying "I think I have damage" over the radio.
However, McLaren was slow to react, not calling Piastri into the pits until the end of the second lap.
Why it matters for Oscar Piastri
By the time Piastri emerged from the pits with a new front wing and fresh hard tyres, he had dropped down to 21st.
Andrea Stella, McLaren's team principal, admitted that Piastri's race was "ruined" by the opening-lap incident.
What comes next?
Despite the setback, Piastri recovered to finish 11th, narrowly missing out on points, aided by retirements, penalties, and a late safety car.
Lando Norris, Piastri's teammate, finished fourth, while Ferrari's Charles Leclerc won the race.
McLaren has some major upgrades planned for Hungary, which Stella hopes will help close the gap to the front-runners.
Norris complained that McLaren's MCL40 lacks grip and downforce to compete with Ferrari and Mercedes.
The team will look to bounce back at the next race, with Piastri aiming to score his first points of the season.
On Sunday, Piastri got off to a promising start at Silverstone, surging past Norris before the collision.
Lawson had lost speed after dipping into the gravel, causing Piastri to make soft contact with the back of his car.
The incident highlighted the need for McLaren to improve their strategy and reaction time to incidents on the track.
Piastri's finish of 11th on Sunday was a disappointment, given his strong qualifying performance.
He will look to regroup and push for a better result at the next race, with the aim of scoring points and moving up the championship standings.
