Jockey Jason Maguire has been brought out of an induced coma after he had part of his liver removed following a fall at Stratford on Monday.
The Grand National-winning jockey was unseated while riding Scots Gaelic and kicked in the stomach by another horse.
The Irishman, 33, was airlifted to University Hospital Coventry, where X-rays revealed he suffered a fractured sternum and bleeding on his liver.
Maguire had been due to ride at the Cheltenham Festival this week.
His agent, Chris Broad, said the surgeon had been happy with the way Maguire's operation went.
Broad's wife, Jane, added: "Jason has been brought round out of his induced coma throughout the day.
"I think he's very aware of who's around him - his wife Lauren, as well as Chris - and he's had a few other very close friends in to see him.
"At the moment, fingers crossed, it's going in the right direction."
Maguire, the nephew of former jockey Adrian Maguire, rode Ballabriggs to victory in the 2011 Grand National at Aintree.
