Bagnaia was involved in a horrific incident on the opening lap of the grand prix while leading, after he was flung from his Ducati exiting Turn 2.
The world championship leader then had his leg run over by KTM’s Brad Binder, who could do nothing to avoid him.
Bagnaia, along with team-mate Enea Bastianini – who triggered a pile-up at Turn 1 – was taken to the medical centre, before being transferred to hospital.
Bagnaia is thought to have largely escaped any serious injuries, with the Italian undergoing scans to confirm he has not suffered any fractures to his leg.
Bastianini, meanwhile, is thought to have suffered fractures to his hand.
Espargaro was left to start effectively from pole for the restarted 23-lap grand prix, which he won from Aprilia team-mate Maverick Vinales to lead the marque’s first ever 1-2.
The Spaniard, who also won Saturday’s sprint, dedicated his victory to Bagnaia, while also explaining that the wind caused him numerous issues with his riding style – forcing him into several mistakes, one of which dropping him 1.3s adrift of Vinales at one stage.
“I’m speechless,” Espargaro said in parc ferme.
“First thing I want to say is I’m happy, really, really happy that nothing [serious] happened today on the first start.
