Former Formula 1 driver Mark Webber is in a "satisfactory" condition after being injured in a crash in a World Endurance Championship race in Brazil.
The Australian, 38, who quit F1 last year after 12 years, was racing for Porsche in the Six Hours of Sao Paulo.
Race organisers said there had been a "serious" collision between his car and the Ferrari of Italy's Matteo Cressoni.
A statement on Webber's website said the driver remained in a local hospital overnight "for precautionary checks".
The FIA, motor sport's world governing body, said the race ended under the safety car following the accident.
The FIA added: "Both drivers were taken to the circuit's medical centre and, after initial examination, to the local Hospital Bandeirantes for further checks, their condition has been reported as satisfactory."
Webber's former F1 teams include Williams and Red Bull, where he raced alongside four-time world champion Sebastian Vettel. He enjoyed nine grand prix wins in his 12-year career.
British F1 driver Jenson Button tweeted: "Glad to see @AussieGrit is OK after his shunt at Interlagos @FIAWEC, that was a big one matey."
