Jorge Martin (Aprilia Racing) is confirmed to miss the PT Grand Prix of Thailand after suffering fractures in his left hand in a training crash ahead of the season opener.
The #1 was preparing for the Thai GP after being sidelined from most of pre-season testing following his crash on Day 1 of the Sepang Test.
He will undergo surgery on his left hand - not the one he broke in Malaysia - on Tuesday in Barcelona, with recovery times to be determined after surgery is complete.
Aprilia have confirmed that Lorenzo Savadori will sub for the reigning World Champion at Round 1.
