Alex Albon spent a night in intensive care after suffering complications following his appendix surgery in Italy.
The British-Thai racer missed the Italian Grand Prix, with Nyck de Vries filling in for him at Monza. Williams said he had been diagnosed with appendicitis, and would be undergoing surgery to resolve the issue.
That laparoscopic procedure was completed successfully on Saturday lunchtime, but later in the day he suffered a post-op complication. That led to respiratory failure, Williams have revealed, which saw him intubated and taken to intensive care for the best possible treatment.
