Williams driver Valtteri Bottas was ruled out of competing in the Australian Grand Prix on Sunday due to a back injury suffered in qualifying for the Formula One season-opening race.
The Finnish driver suffered what the team called 'soft tissue damage' in his lower back during Saturday's session.
After being treated by medical staff at the track, he was taken to the Alfred Hospital adjacent to the Albert Park circuit and spent the night there.
He returned to the track on Sunday and underwent treatment from a physiotherapist but the official FIA medical delegate said he was not fit to drive.
"The team respect the FIA's decision and will now work with Valtteri ahead of the Malaysian Grand Prix to ensure he receives the treatment required to get him back to full fitness," Williams said in a statement.
Bottas had hoped that he would be able to race.
"I have done a lot of work since the issue with my back came in qualifying to get myself ready, starting treatment immediately, so the news that I couldn't race was obviously disappointing," Bottas said. "I now have two weeks until the next race to receive further treatment to ensure I will be back to full fitness and even stronger in Malaysia."
