Alex Albon admitted "it's going to be tough" to be fit in time for the Singapore Grand Prix after suffering post-surgery complications last weekend.
The British-Thai racer pulled out of the Italian Grand Prix after being diagnosed with appendicitis last Saturday. He went under the knife at a local hospital that same day, and the surgery was successful.
However, he later suffered a complication which led to respiratory failure. He was re-intubated by doctors and taken to intensive care, where fortunately he made "excellent progress". He was then taken back to a general ward, and allowed to return home on Tuesday.
