Max Verstappen will not be in Jeddah on Thursday. The driver has a stomach illness and will not be in there until tomorrow, with the FIA granting permission for this.
A tweet from Red Bull revealed that the driver has stomach illness. Verstappen himself says he is already feeling much better, so we need not fear that he will not drive this coming weekend. The driver had to postpone his flight and will not be in Jeddah until tomorrow. The FIA has permitted this.
