Mick Schumacher, the 16-year-old son of seven-time Formula 1 world champion Michael, suffered a broken hand during an ADAC Formula 4 crash at the Red Bull Ring on Sunday morning.
Schumacher, who won on his first-ever car race weekend at Oschersleben in April, was battling with Austrian teenager Thomas Freining when he was pushed from behind into the pitwall at the start of the final lap of race two.
As Freining first looked to Schumacher's inside, he then swerved left, striking Schumacher in the gearbox and pushing him into the wall. Freining was given a 30s penalty for his part in the collision.
Schumacher – who came into the weekend fifth in points – was subsequently taken to hospital as a precaution.
Upon medical examination, it was found that he had a fracture of his right hand. This has ruled him out of today’s third race and puts his participation in the next round at Spa in a fortnight’s time in doubt.
The race was red flagged and backdated to the previous lap, classifying Schumacher in 10th position.
Schumacher had also crashed out of Saturday’s opening race, taking both front wheels off his car on the approach to the second corner.
