Defending MX2 world champion Jorge Prado has been ruled out of this weekend’s British grand prix at Matterley Basin after injuring his shoulder in training.

The 18-year-old Spaniard won both motos in Argentina’s opening round, however an incident a fortnight ago has become more severe than initially expected.

“After such a strong start to the season for the team and Jorge it is disappointing for everyone that he and Jeffrey [Herlings] are now missing Matterley Basin and the first European round of 2019,” said Claudio De Carli, Red Bull KTM team manager.

“Unfortunately this is part of the sport but, fortunately, it could be worse and we hope Jorge will be back on the bike very quickly. We’re in good shape and we are confident, and we believe this will not be such a big setback for us in what is a long season.”

A detailed medical examination in Belgium revealed a haematoma under the left shoulder blade was causing the discomfort experienced while he tried to continue training. He’s now been advised to rest and will potentially return for Valkenswaard.
