Valtteri Bottas continues to make progress towards returning to action in the Malaysian Grand Prix.
The Williams driver was declared unfit to race in the season-opening event in Australia after injuring his back during the qualifying session.
Williams said the Finn's injury was an annular tear in his lower back.
Bottas is still working on his recovery to return to the cockpit at Sepang, and said on Friday he's making good progress.
"Progress is being made and every day is a good step forward," said Bottas. "Can't wait for Malaysia!"
