Roberto Rolfo who celebrated his 100th World Superbike presence at Magny Cours last weekend has broken his kneecap.
The Pedercini rider was out training with his bicycle on Monday and fell sustaining a compound fracture to his left patella (kneecap).
The Italian has already undergone surgery and will miss the last round of the World Superbike season at Portimao next weekend.
Rolfo returned to WSBK racing this year and is currently 18th in the standings, and at the moment there is no news whether Pedercini will find a replacement rider.
