He hit the ground heavily and took some time to get to his feet, while his Honda was wrecked in the resulting roll it took through the run-off area â with the rear of the bike ripped off.
Marquez was taken to the circuit medical centre for initial checks, before being transferred to the local hospital for further assessment on his left leg and back.
Speaking to the press in Thailand, Puig confirmed Marquez escaped injury and will âcontinue with the planâ in this afternoonâs FP2 session.
âHe had a big crash as you all saw, but fortunately he’s okay,â said Puig.
âWe went to the hospital to check everything, they did an MRI and everything looks fine. Of course, he had some contusions in the back and also in the leg, and also here in the hip a little bit, but nothing to be worried of.
âWe were lucky for today. We will continue with the plan, and he will have some treatment probably, and he will go out and we will try to continue with our plan.â
Puig theorised that Marquezâs crash was caused by him accumulating dirt on his rear tyre from running off line on the straight between Turn 2 and 3, as he was not going at speed at Turn 7 and the tyre was up to temperature.
âThe thing is that on the back straight, probably he was not on the correct line, he was on the outside line,â Puig added when asked what caused the crash. âLooks like that area is a little bit dirty, and probably the tyre got some dust there and this caused [the crash].
âItâs one possibility, the tyre was not completely clean, that was probably the reason for the crash, because he was not fast, the tyre was on the [optimal] temperature.
âSo, it was a matter of that there was probably some dust or dirt on the tyre.â
Marquez comes into this weekendâs Thai round 98 points clear in the standings, and only needs to outscore nearest rival Andrea Dovizioso by two points on Sunday to secure his sixth MotoGP world championship.
