Yonny Hernandez is to miss the first Sepang test. The Colombian rider crashed while riding dirt track, falling heavily on his left shoulder, and dislocating the shoulder. As a result, Hernandez will not be able to ride at Sepang, and will be replaced by Ducati’s test rider, Michele Pirro.
The good news for the Pramac Ducati rider is that the damage was mainly microfractures, and the ligaments and tendons were undamaged. The shoulder is a very complex joint, held together by a complicated network of tendons, cartilege and ligaments which allow it to move freely, but is vulnerable to damage.
