Dual MotoGP World Champion Jorge Lorenzo has undergone surgery on his left collarbone and right thumb in preparation for the 2014 title chase.

The Yamaha Factory Racing rider has suffered a series of collarbone injuries over the course of his career, with heavy crashes at Assen and Sachsenring this year resulting in damage to his left collarbone.

The latest operation saw the removal of 11 screws and the titanium plates fitted after Lorenzo’s 2013 Sachsenring crash, meaning the bone can now heal more completely.

The 26 year-old also had a small procedure performed on his right thumb, further to an injury sustained in 2010.

Surgeons Dr. Joaquin Rodriguez, Dr. Ana Carreras and Dr. Marc Cots carried out the operation on Lorenzo at the Hospital General de Catalunya, in Sant Cugat just outside Barcelona, with the rider’s personal doctor, Teresa Sola, also in attendance.

Lorenzo was given the all clear to leave the hospital on Tuesday after remaining there overnight and will be re-examined before the end of the month. He then plans to resume full training early in 2014 to be ready for the first MotoGP test in Sepang after the winter test break.
