Checa may miss race after huge highside.

Marlboro Yamaha Team riders ended today's final qualifying with contrasting fortunes - Biaggi just a fraction off the front row while Carlos Checa suffered a huge highside during the late stages of the session.

Checa crashed as he accelerated through turn three, a medium-speed left hander. The Spaniard was flung through the air, landing heavily in the gravel trap. The high-speed crash left Checa battered and bruised all over and though x-rays have confirmed that nothing is broken, he has yet to decide whether he will race tomorrow.

"It was a big highside but I can't remember exactly what happened," said Checa, who had been running tenth quickest. "I fell heavily and I've hurt a shoulder and a foot, in fact I hurt everywhere, but the main thing is that I've not broken anything. It's too soon to say whether I'll race or not. We'll analyse exactly what happened and see how I feel in the morning before we make any decisions."

Hiroya Atsumi, Marlboro Yamaha Team director, added: "I feel sorry for (Checa), it was a big crash, and we're just hoping he's okay. I think he was going for his fast lap a little too early, but he's a rider, he was just very keen to improve his times."
