The 23-year-old Espargaro suffered discomfort in his right arm during Sunday's French GP at Le Mans, and a loss of force in the early stages of the race.
It was not the first time that the Yamaha rider has suffered from the problem, having reported pain at Jerez at the beginning of the month, for which he was receiving physiotherapy. As such, it was decided that he should go under the knife without delay in order to give him sufficient time to recover ahead of the next stop on the MotoGP calendar at Mugello on May 31.
"I had noticed this discomfort in my arm after some events before and I thought that it would get better quickly after the end so the race, but it didn’t," explained Espargaro.
"Therefore I went to visit a physical therapist about the discomfort I had in my right forearm after Le Mans and we quickly discovered that I needed to see a specialist. We decided to reduce the time between consultation and surgery, with the doctor Angel Villamor, in order to have as much time as possible between the operation and the next race.
"The truth is that I had experienced that sensation before but I did not consider it important, but unfortunately in these last two races it has been a little more serious. In Jerez, I believed that I suffered pain due to the type of circuit and the effort that I made during the first few laps trying to follow Lorenzo and Marquez and then Rossi and Crutchlow. Yet, in Le Mans it was even worse because I struggled very early in the race being nearly unable to ride the bike.
"Fortunately, the operation went well and I can now start working again in order to get in the best possible physical condition for the upcoming races."
Aleix Espargaro underwent surgery on his thumb on Tuesday after damaging ligaments in a crash during free practice on Saturday.
