Motegi (Japan), Oct 18 (IANS): Spain's Jorge Lorenzo on Thursday said he was disappointed over the possibility of not being able to participate in the upcoming Japanese MotoGP in Motegi.

Lorenzo, who suffered a dramatic crash during practice in Thailand, was officially passed fit to take part in the race this weekend but said he was unsure of racing as he has not yet fully recovered, reports Efe.

"I am very disappointed because I knew the fracture existed after the scan but I thought after 13-14 days the injury would improve and I would feel much better here," Lorenzo said in the pre-race press conference.

"In the first days I felt some improvement, that is why I started to swim and make some exercises, but when I slightly force the wrist, I feel quite a big pain after some hours," he added.

"The wrist is quite inflamed, the feeling is not good, the pain is quite big, (when) making some movement," said the rider from Mallorca.

Lorenzo said Motegi was one of his favourite circuits and he was going to test himself in practice on Friday, adding that his participation depended on the rate of recovery.
