Lewis Hamilton is recovering from fatigue and mild dizziness after charging through the field to take third place at the Hungarian Grand Prix.
After a strategic error left the Mercedes driver in 14th at the Hungaroring, Hamilton battled his way back to the podium, where he was seen to be physically exhausted, struggling to take part in the celebrations for Esteban Ocon's first win.
Hamilton was absent from the beginning of the FIA podium press conference, with the fatigue and dizziness symptoms revealed.
Mercedes team principal Toto Wolff said: "I haven't spoken to him yet. The doctor is with him.
"I think you can just relate to the heat out there and the race that he had with tonnes of overtaking, that is exhausting. I think he should be alright but better to be safer than sorry."
