The Austrian Grand Prix was halted with 20 laps to go when a red flag was brought out after Franco Morbidelli's Yamaha collided with the Avintia Ducati of Johann Zarco at the Red Bull Ring in Spielberg on Sunday.
As the field approached turn three, Morbidelli's front wheel hit the back of Zarco's bike as both went down, with the bikes flying across the track and nearly taking out other riders at the turn.
Yamaha's Maverick Vinales and Valentino Rossi had a lucky escape, especially the latter as one of the cartwheeling bikes flew past the front of his bike as he slowed down and the veteran looked visibly shaken when he went back to the garage.
Morbidelli was able to walk away from the crash and was escorted to a waiting ambulance while Zarco also looked okay as he returned to the garage.
Ducati's Andrea Dovizioso won the race.
Dovizioso, who said on Saturday that he would not be renewing his contract with Ducati, took the chequered flag to keep the team's perfect record at the Red Bull Ring intact.
Ducati have won every race since the circuit was introduced on the calendar in 2016 and it was the Italian rider's third victory on the track having won in 2017 and 2019 while it was Ducati's 50th premier class win.
However, the manufacturer lost out on a one-two finish when Joan Mir capitalised on Jack Miller's mistake on the final lap as his Pramac Ducati went wide to give the Suzuki rider second place
