Martin Dwyer is hoping to be back in the saddle in time for the Breeders' Cup at Churchill Downs in November.
The Derby-winning jockey is on the sidelines after undergoing two operations to repair the damage to his elbow and thumb sustained when he was unseated by Red Lite in the second division of the Aston Flamville Fillies' Nursery at Leicester on Monday.
It was thought he would miss the remainder of the season, but Dwyer wants to be back riding in time to partner Dangerous Midge in the Breeders' Cup Turf on November 6.
"I've only got the use of four fingers, which is making life interesting," he explained.
"I broke the thumb and the hand below my thumb. It's been operated on and they've rewired it because it was a bit of a mess - a bit like a Crunchie bar, the surgeon said.
"It looks as though the season could be finished, but the consultant said he would try to get my elbow out of plaster next week to get physio straight away. It depends on how the operations have worked and I'll take it week by week.
"If Brian is running a horse in the Breeders' Cup, I'd love to be back by then, which isn't out of the question.
"I've got six weeks, so I'll know in a couple of weeks whether that is achievable. But it gives me something to aim for."
