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.
Speaking to Spanish television, Doctor Angel Charte says Bagnaia “is fine” and appears to have escaped serious injury.
He is to undergo a CAT scan today to check “a small injury” that has been detected, to determine whether it’s old or new.
“Pecco is fine,” Dr Charte told DAZN.
“He had a severe polytraumatism. A motorcycle has passed over his femoral and tibial area.
“We have taken an X-ray and we have detected a small injury that we don't know if it is current or old.
“We need to do an urgent CAT scan, which will be done at the Hospital General de Catalunya. At cranial and thoracic level everything has been normal. He was oriented [conscious].”
