Ben Spies admitted that he would go into the Indianapolis MotoGP race day in substantial pain after his crash in qualifying.
Until his accident, Spies had been on a lap that looked set to place him on provisional pole, although in the end he could only qualify fourth.
The American expects to try and race, despite his discomfort.
"My shoulder is really sore after that crash, maybe some torn ligaments so it's pretty painful," said Spies.
"I'm getting some treatment and we'll see how it is tomorrow."
Spies did not think there was any major problem at that section of the track other than a difficult surface.
"The track surface is pretty tricky at the end there, it seems to have caught a few people today," he said.
He added that the biggest blow from the crash was that it came at a time when he was looking very competitive.
"It's frustrating as we've been going really well all weekend and I've been feeling really confident with the bike," said Spies. "I think we could have been on pole."
