Fernando Alonso is "conscious and well in himself" after the two-time Formula 1® world champion was involved in a road accident while cycling.
Alonso, 39, is set to return to F1® with the Alpine team this season, after a two-year absence, though there will now be doubts over his participation at the first race in Bahrain next month.
The Spaniard won successive F1® world championships in 2005 and 2006.
On Thursday, Apline confirmed in a statement that Alonso had been involved in an incident while cycling in Switzerland.
However, the statement did not confirm if Alonso was in hopsital.
It read: "Fernando is conscious and well in himself and is awaiting further medical examinations tomorrow [Friday] morning.
"Alpine F1 Team will not make any further statement at this point in time. Further updates will be given tomorrow."
