The Grupo Francesco Hernando MotoGP team will not replace the injured Sete Gibernau at this weekend's Italian Grand Prix at Mugello.

Gibernau fractured his left collarbone in a practice accident at Le Mans and will be out of action until at least round six, to be held at Barcelona on June 14.

The withdraw means that the Italian Grand Prix grid has been reduced to just 17 riders.

36-year-old Gibernau returned to MotoGP this season after two years in retirement, and had been approaching full strength in his left shoulder after ligament damage during pre-season training.
