Briton Jenson Button was transferred to hospital in Mannheim after complaining of eye problems during this afternoon's second practice session for this weekend's German Grand Prix.
The 2009 world champion, who drives for the McLaren Honda team, was sent to hospital by the circuit medical centre at the Hockenheimring after complaining of an eye irritation.
A team spokesman said: "Jenson complained of an eye irritation during FP2 and he has gone to Mannheim hospital to have a precautionary check-up."
The team's reserve driver Stoffel Vandoorne, who replaced two-time champion Fernando Alonso at the Belgian Grand Prix in April, is on stand-by.
