Jorge Lorenzo has revealed he has suffered a broken right rib, which is a legacy of his heavy FP3 crash during the MotoGP Qatar Grand Prix weekend.
Lorenzo was flicked from his Honda in the opening stages of Saturday's third practice at Losail at Turn 6, and was taken to the medical centre for checks before being passed fit to continue.
He ended his Honda debut 13th, as pain in his shoulder from his FP3 crash and an early clutch issue hindered his progress.
Lorenzo admitted he would undergo further checks on his shoulder this week, though revealed in a brief Twitter post he had in fact suffered a broken rib on his right side.
He has been issued a recovery time of at least three weeks by doctors, but insists he will still “fight” at the Argentine Grand Prix in two weeks' time.
His Twitter post read: “TAC done. Fissure of the first rib on the right side, three weeks/one month to recover. We will fight in Argentina!”
Lorenzo has endured a bruising winter, after he broke his left scaphoid at the end of January. This forced him to miss the first test of the year in Malaysia.
The triple MotoGP world champion has not been fully fit since September's Aragon round, as he suffered a broken foot in the Aragon race and a broken left wrist in a crash during practice for the Thailand Grand Prix.
