Reigning MotoGP world champion Casey Stoner hopes to be back in action tomorrow after missing the first day of the Sepang MotoGP test in Malaysia.
Stoner felt his back lock up when he was warming up, minutes before he was due to ride the RC213V with the number one plate for the first time.
“I was stretching this morning for a good 20 minutes preparing to go out on track for the first time and then all of a sudden my back just locked up on me, I couldn't move or do anything,” said the Australian.
“I had to call someone to come and help me move into a position that was less painful. Then I had some physio on it straight away trying to get it better for this afternoon but it wasn't feeling good.
“I had some more physio after lunch but it still wasn't easing up. I felt I could have gone out on the bike in the afternoon but we all agreed it would probably make it worse for tomorrow,” he added.
“We have two more days testing here in Sepang, we know the track well and we are getting to know the bike, we just need some time to test the new parts we have here to give feedback to HRC.
“I think tomorrow the track conditions will be better and as long as my back improves overnight we should get back on schedule with our testing programme tomorrow.”
Stoner's team-mate, Dani Pedrosa, posted the second fastest time of the opening day behind pace-setter Jorge Lorenzo on the factory Yamaha YZR-M1.
