Ducati MotoGP rider Andrea Iannone has discovered a further arm injury following his recent testing crash, but is committed to racing in this weekend's Italian Grand Prix at Mugello.
Iannone crashed at the Italian track during a test on the eve of the recent Le Mans race and was immediately diagnosed with a dislocated shoulder.
Despite this, he finished fifth in the French GP that weekend following a huge battle with Marc Marquez.
He has now revealed that further checks undercovered a fracture to the tip of the humerus in his left arm.
"On Sunday I will race at Mugello but it's going to be difficult for me to be 100 per cent fit," said Iannone.
"A couple of days ago I stopped taking painkillers and yesterday I did an MRI scan.
"Unfortunately they found a hairline fracture at the tip of my funny bone, and to be sincere that was a bit of a nasty surprise.
"The swelling still causes me a lot of pain and I am continuing to do laser therapy in an attempt to get it to go down as soon as possible.
"In any case, I'll have to grit my teeth like I did at Le Mans, because it's far too important for me and for Ducati to have a good race in front of the Mugello fans."
Ducati will expand to a three-bike line-up for its home grand prix, with test rider Michele Pirro making his first racing appearance of the year alongside Iannone and Andrea Dovizioso.
