Hadjar disqualified as Red Bull apologises for error
Red Bull Formula 1 driver Isack Hadjar has been disqualified from Miami Grand Prix, forfeiting a ninth-place start.
Hadjar had advanced to Q3 in Saturday's qualifying, placing ninth - four places and just under a second back from team-mate Max Verstappen.
But his starting position was quickly put under threat by a post-session investigation over a potential floor legality breach, with a likely disqualification looming.
This has now been confirmed. The stewards said Red Bull "did not dispute the findings of the technical delegate that portions of the left-hand side and right-hand side floor boards were protruding 2mm out of the reference volume".
"We made a mistake and we respect the decision of the stewards," team boss Laurent Mekies was quoted as saying by Red Bull.
"No performance advantage was intended nor gained from this error. We will learn from this incident and assess our processes to understand how it occurred and to take steps to ensure it cannot happen again. As a team, we apologise to Isack, and to our fans and partners."
