Just hours after being officially named as Danilo Petrucci's replacement for the French MotoGP, Luca Scassa has been ruled out of the Ioda ride by a broken femur while testing at Mugello.

The Pedercini Kawasaki WSBK rider had been trying to re-familiarise himself with the latest Open class version of the Aprilia ART, which he previously rode in 'CRT' guise during five stand-in appearances for Cardion AB last year.

But it all went wrong when the 29-year-old suffered a highside fall at turn two, leaving him with a broken right femur, for which he will require surgery.

The Ioda team, which has only a single MotoGP entry, is now debating whether to withdraw from Le Mans or try and find a second stand-in for Petrucci, who is himself recovering from a broken wrist and dislocated left arm following a warm-up fall at Jerez.
