Correa, 20, suffered a spinal injury and broken legs during the support race for the Belgian Formula 1 race.
The American subsequently underwent a four-hour operation in Liege.
“He will continue his recovery in the care of a specialist team,” said a statement from his Sauber Junior team.
Hubert, who was 22, suffered a huge impact from Correa’s car, which was travelling at about 170mph, at the Spa-Francorchamps circuit.
The Frenchman was taken to the medical centre following the incident, and died shortly after.
