MXGP contender Jorge Prado has undergone successful surgery following his clash with teammate Jeffrey Herlings in Germany, uncertain when he will be fit to return.

The Red Bull KTM Factory Racing duo engaged in a race-long battle during moto one at Teutschenthal, Prado ultimately taking victory before the incident occurred over the finish.

Prado copped a handlebar deep into his arm-pit in the impact and, while an operation was completed Sunday night, he has stated that the extent of his injury is still somewhat unknown.

“As you know, after winning the first moto at the [German] GP, Jeffrey and I collided after the finish line, digging the handlebars deep into my arm-pit and having to undergo surgery that same night,” Prado posted on social media. “Fortunately everything went well, but I don’t know the real extent of the injury.”

Prior to missing the second moto at the MXGP of Germany, Prado was in contention to challenge for a maiden MXGP World Championship, sitting just 12 points adrift of the red plate entering round 11.

The former MX2 world champion is now 31 points adrift of points leader Tim Gajser (Team HRC Honda), meaning if he were to miss another race it would effectively rule him out of title contention.

The next round of the MXGP World Championship is set to take place this Sunday, 10 October, at Lacapelle Marival, France, which marks round 12 of the series.
