Morbidelli, Marquez and Mir set the pace in final practice for the Aragon MotoGP.

World championship leader Quartararo returned to action after his heavy morning fall and was soon back up to speed.

Qualifying 1, for those outside the top ten after third free practice, will now get underway.

Valentino Rossi has been forced to miss this weekend's event after a positive Covid test on Thursday. The Italian is also expected to miss next weekend's second Aragon round.

HRC test rider Bradl is again replacing injured reigning world champion Marc Marquez.
