MotoGP newcomer Loris Baz sustained a neck injury after coming off on his first flying lap in FP3 at Aragon, ruling him out of the remainder of the session.
However, the French rider was back in action in FP4 on the Forward Yamaha and later qualified in 22nd position, more than four tenths behind top Open rider Eugene Laverty.
Baz revealed afterwards that he was in pain with his neck injury in qualifying but is optimistic he can challenge for the Open class honours on Sunday.
“Too bad for the fall this morning. I made a small mistake and found myself helplessly on the ground,” Baz explained.
“I lost the whole session and I suffered a painful muscle contracture in the neck. In qualifying I was not in top form, I still had pain and I preferred not to risk.
“I'm starting behind the other riders, but we are not far from the other Open and I think we can go for it tomorrow.”
Baz is leading the Open class standings by five points from Hector Barbera after a shock fourth place last time at a wet-dry Misano.
New team-mate Toni Elias was 25th fastest on the second of the Forward Yamaha machines and starts at the back of the grid.
