British Moto2 star Scott Redding and Ducati's Nicky Hayden both suffered with a mystery hand numbness during their respective races at Catalunya yesterday.

Redding was involved in the battle for the lead in the early stages of the race, but dropped off the back of the leading group when his right hand went numb and made it difficult for the 19-year-old Briton to brake and open the throttle with any feeling. He dropped back to try and recover feeling in the hand, but no improvement was forthcoming and he was forced to defend tenth place to the finish.

"I got away from the line okay, but then I started having problems with my throttle hand. When I was tucked in on the bike it started to go numb, as if something was pressing on a nerve somewhere. I let a couple of people through so that I could relax a bit and see if it improved, but it just wouldn't go away. It meant I was struggling with feeling, both on the gas and on the brakes, which was losing me time in every corner," said the Briton.

Hayden, meanwhile, suffered the problem in qualifying and said: "I felt it a little bit in qualifying yesterday, so we did some treatment last night with the team physio, but the problem returned in the race. I’ve had it happen a couple of other times in my career, and around here, with so much hard braking, I could hardly feel the brake lever or the throttle. On the straightaway, I could move my fingers and get some feeling back, but then it would return."
