Sainz spun off the track at Turn 7 in Miami during second practice on Friday, hitting the concrete wall on the right-hand side of the track in an impact that left him suffering from some neck pain.
Despite Sainz’s suggestion in the drivers’ briefing that a TecPro barrier should be installed at the corner, FIA race director Niels Wittich took no action, leading to frustration when Ocon crashed at the same corner in qualifying with a 51G impact.
