Welsh jockey Sam Twiston-Davies hopes to be out of hospital soon following One More Go's fatal fall at Chepstow at the weekend.
Davies was taken ill at home on Sunday, a day after the incident in a handicap hurdle race.
"It was a grade four laceration of the spleen. They like to observe it for a good period of time because it's quite dangerous if it re-bleeds," he said.
"Hopefully with a bit of luck we can go home soon," said Twiston-Davies.
"It's one of those things which sadly happens in racing.
"At the end of the day you're on the back of a horse so injuries are part and parcel with the job but there's no reason why I can't come back better than before."
The National Hunt jockey, who is retained by Paul Nicholls, has ridden 70 winners so far this season and sits in second place in the Jump Jockey's Championships.
He rode two winners at Chepstow over the weekend, before he fell from the Dr Richard Newland-trained One More Go.
Twiston Davies could be out of action until November.
He initially went home after the fall, but later had to be admitted to hospital in Gloucester.
"I've had a great start. Paul's horses have been running really well," he said.
"It's always disappointing these kind of things happen at this time of the season because it's just starting to get busy but hopefully there's lots to look forward to."
Twiston-Davies has his sights on a return in time for the Cheltenham's three-day open, starting on 11 November.
"There's lots of big races there, plenty of graded races, so I'll try and get back before then if I can," said Twiston-Davies.
"It is what it is, we can't rush these things at the same time we'll be doing everything we possibly can to get back in a good a shape as possible."
