Indianapolis: Mahindra Racing had to endure a tough time at the Indianapolis Grand Prix, with Danny Webb missing the 125cc race due to a hand injury and Marcel Schrotter crashing on the final lap after being in the points contention for much of the race.

Briton Webb had injured his hand in Saturday's morning practice and that affected his performance in the qualifying.

After taking medical advice, Webb decided to sit out of the GP with the hope of being fit for next week's San Marino Grand Prix in Misano, Italy.

Schrotter began the race quickly as he gained two places, after starting from 15th, within the first four laps.

He was well into the points on the ninth lap when he began to struggle with grip. He eventually fell on the 24th and final lap while battling for points.

"It's really a shame, because I think I was up as high as 13th place and with everything that was happening on the last lap I might have been able to finish even higher," Schrotter said.

Webb was still doubtful for next race.

"They did an x-ray on Sunday, but it was with a portable x-ray machine. They said it wasn't broken, but all of the doctors at the Clinica Mobile felt around and they seem to think it's broken.

"I prefer to be fit towards the end of the season, have a good end, rather than come back too quickly. We’ll see what happens. Hopefully I can be ready for Misano. If not we'll have to wait," he said.
