Alex Rins has opted against contesting the remainder of the Japanese MotoGP weekend after enduring a ‘painful’ first day back on the LCR Honda in Friday Practice.

The Spaniard made a long awaited return to track action at Motegi after a seven-event, three-month lay-off from a leg injury sustained in an accident during June’s Italian MotoGP at Mugello.

However, after admitting on Thursday he would be prepared to stop if he felt too uncomfortable on the Honda RC213V, he has now confirmed he won’t make it out on track for the remainder of the weekend after being declared unfit by medical staff.

He becomes the fourth full-time rider to opt out of competing in this weekend’s Japanese event with VR46 Ducati’s Luca Marini and Gresini Ducati’s Alex Marquez also sidelined by injury woes sustained last weekend in India.

Enea Bastianini remains on the sidelines from injuries he picked up in Catalunya.
