Marc Marquez will undergo surgery this week after further injuring his right shoulder in a crash during day one of MotoGP testing at Jerez.

The reigning champion immediately visited the medical centre after his crash on Monday where it was determined he suffered a partially dislocated shoulder, however he returned to riding that afternoon before topping the timesheets on day two.

Marquez has since revealed he sustained the same injury during his crash at the Malaysian grand prix, prompting him to undergo surgery as a preventative measure.

“This winter I would have liked to have a nice holiday and enjoy a bit of quiet time after a great 2019, but it is time to have surgery on the right shoulder,” Marquez explained. “As everyone knows, last winter was very tough for me with the operation on the left shoulder, which was very, very damaged.

“I want to avoid the situation where my right shoulder is in this condition in the future so I spoke a lot with the doctors to see what our options were. Before Motegi I had some issues with the shoulder and then after the crash in Malaysia I had a subluxation.

“Here at the test I had another subluxation after the crash, so we decided with the doctors that it was best to have the surgery to avoid the situation we had with the other shoulder. It will take more or less the same time and we will work in the same way to arrive at the Malaysia test as strong as possible.”

The 2020 Sepang test is scheduled for 7-9 February, which the Repsol Honda rider is likely to recover in time for.
