Yamaha Tech 3's Jonas Folger will sit out the Japanese GP and return immediately to his native Germany for medical checks.

The Clinica Mobile medical staff examined Folger on Wednesday and recommended that he undertake further tests in Munich, with his participation in the next two rounds being doubtful.

The entire team have wished the German a swift and full recovery. 

"I came to Japan and was motivated for these three flyaway races, but I’ve been feeling really weak since the Misano and Aragon rounds." Said Folger

"On arrival here, I have been struggling with my energy levels, even leaving the hotel room was impossible for me, and unfortunately, I had to miss some Yamaha events, which I’m very sorry for."

"I met with Hervé on Wednesday night and we agreed to go for a check with the doctors this morning. I met with Dr Charte and the Clinica Mobile team and they have advised me to return to Germany right away for a series of blood tests." He added

"I’ve had Epstein Barr virus in the past and it’s a possibility that this has flared up again and resurfaced, but we can’t be sure until I’ve had these tests in Munich." 

"I’m really sorry for my whole team and Yamaha at their home race and would like to thank them for all their support. Also sorry to my personal sponsors, I appreciate them all standing by me at this difficult time. Now we must remain positive and aim to come back stronger."
