Avintia Racing's Hector Barbera has undergone successful surgery in Barcelona to counter problems with arm pump, but his participation in the next round of the MotoGP World Championship at Catalunya on June 14 is in doubt.

Barbera, who finished 13th at Mugello on Sunday in the Italian MotoGP, has been experiencing problems in his right forearm at the last three rounds of the championship.

The Spanish rider was treated in the Hospital Universitari Quir?n Dexeus in Barcelona on Monday.

A statement issued by Avintia Racing said: "In the morning he has undergone a nuclear magnetic resonance that showed up his arm pump problem and during this afternoon he had a successful surgery in his right forearm.

"The operation, made by Dr Xavier Mir, has lasted 70 minutes and he used microsurgical techniques to release the extensor and flexor fascia of the right forearm.

"Therefore it was necessary to release the muscles that flex the wrist and fingers, which extends as a double surgical incision."

Barbera is due out of hospital on Tuesday and will begin a programme of rehabilitation next week, with the aim of returning on his Ducati at Catalunya on June 14.

However, the Open class points leader is currently a doubt for the race until his situation becomes clearer next week.
