A serious MotoGP crash at the Catalunya Grand Prix sent Alex Marquez hurtling through the air after a collision with then-race leader Pedro Acosta.

Italian Fabio Di Giannantonio won a dramatic, twice red-flagged Grand Prix of Catalunya on Sunday, the Ducati rider taking his second MotoGP victory and first for three years after horror crashes for rivals Alex Marquez and Johann Zarco.

A depleted field is taking part in MotoGP’s in-season test in Barcelona, with only 19 riders running on track on Monday morning. As expected, both Alex Marquez and Johann Zarco are skipping the test after fractures in Sunday’s race and spending the night in the hospital.
