Mark Webber will spend the night in a local hospital for further evaluation following his heavy crash in the closing minutes of Sunday’s FIA WEC Six Hours of Sao Paulo.

The Australian’s Porsche 919 Hybrid slammed into the wall with 28 minutes remaining in the season-ending race after a suspected failure of some kind to the LMP1-H contender.

According to a Porsche spokesperson, Webber was initially reported to be OK, although he has since been transferred to a local hospital for additional precautionary checks.

He was awake and alert and was deemed to be in satisfactory condition by the FIA doctor on site.

“Mark Webber is in good condition, according to the first information from the doctors,” said Porsche LMP1 boss Fritz Enzinger.

Webber’s co-drivers Brendon Hartley and Timo Bernhard have been to see him in the hospital, according to a post on Webber’s Facebook page.

The cause of the accident has yet to be determined.

Matteo Cressoni, the other driver involved in the accident, has also been admitted to the hospital on precautionary grounds and will be spending the night as well, according to his post on Twitter.
