Medical checks following the US MotoGP have revealed that Dani Pedrosa, initially diagnosed with 'a small fracture in his left clavicle', was in fact riding with a complete collarbone break.

Pedrosa sustained the injury during a huge highside in practice for the previous German round - ruling him out of the race and costing him the title lead, before returning to action less than a week later to claim fifth in Sunday's Laguna Seca race.

The Spaniard wrote in his latest Repsol blog:

"After all of this effort, it was important to know how the bone was, so yesterday, I had a 3D CAT three-dimensional CT scan that confirmed something that did not show up on the first X-rays because of the swelling and because sometimes, there are fractures that give you a restricted view on an X-ray.

"With this 3D CAT three-dimensional CT scan, a week later, we have been able to see that the fracture is a complete fracture. The important thing is the collarbone has not been displaced and that after the effort it is still well aligned, so I will not need to have an operation.

"This is good news, all things considered, so two weeks from now, I will have another medical check-up and I am going to combine the holidays with physiotherapy sessions to recover and reach Indianapolis on form."

The Repsol Honda star sat out morning practice on both Friday and Saturday to rest his shoulder. Pedrosa, now 16 points behind rookie team-mate Marc Marquez in the title chase, has until August 16-18 to recover for the Indianapolis round.

Reigning world champion Jorge Lorenzo, who broke his collarbone at Assen and re-damaged it in Germany, is third in the championship.
