Noel Fehily would like to be back in the saddle at least a week before his intended ride on Kauto Star in the William Hill King George VI Chase on St Stephen's Day.
Fehily has been the main beneficiary of Ruby Walsh's broken leg but he then suffered his own misfortune at Newbury last week.
Initial reports suggested he had broken his wrist when he was unshipped from Rivaliste, but it later transpired that the joint was only dislocated.
"It's a lot better than I first thought and I'm hoping I might get back for Saturday week at Cheltenham," said Fehily.
"I've got to rest it a little bit now and I'll look at doing some physio early next week -- rest, icing and trying to get the swelling down and the bruising out.
"That's the main thing for now and then I'll look at stepping it up next week and get it as well as I can.
"It's the middle of the season so fitness won't be a problem, I'll keep ticking over.
"I would definitely like to be riding a week before the King George, just to get my eye in.
"It was terrible luck. Friday night was pretty grim. The doctor wasn't at all positive, and I wasn't getting great vibes off him.
"But when I went back to see him the next night he was a lot more positive and the next day I couldn't believe the news I was getting, it was brilliant.
"I'm not in pain now. I was at the time but every day it is improving, that's always a plus.
"I can't wait to be back, it's a great time of year and it's what we do it for."
Sam Twiston-Davies, meanwhile, will be allowed to ride Little Josh at Cheltenham on Saturday week following the move of the Tingle Creek Chase to Prestbury Park.
Twiston-Davies was due to serve a three-day suspension, which would have seen him miss the mount on the Paddy Power Gold Cup winner, who is trained by his father, Nigel, in the December Gold Cup.
But with the Grade One Tingle Creek having been switched to Cheltenham due to Sandown's abandonment on Saturday, the young rider is eligible for the ride under British Horseracing Authority regulations.
BHA rules stipulate that Twiston-Davies can defer his suspension, which falls under the four-day threshold, on days in which Grade One races are being staged.
The up-and-coming jockey was given a three-day ban, which he failed to overturn following an appeal yesterday, after being found guilty of careless riding on Mad Moose at Kempton last month.
