Champion jockey Jim Crowley has been discharged from hospital following his involvement in a four-horse fall at Kempton, but fellow rider Freddie Tylicki remains in intensive care.
During the third race of the flat meeting, Tylicki's Nellie Dean went down heavily after seemingly clipping the heels of Madame Butterfly.
Crowley on Electrify, Steve Drowne on Skara Mae and Ted Durcan on Sovrano Dolce were close behind and were also tangled up in the fall.
Crowley and Tylicki were subsequently taken to hospital in nearby Tooting with suspected spinal injuries.
The meet was abandoned but the Injured Jockeys Fund later released an update on the condition of both riders.
"Following the incident at Kempton Park racecourse this afternoon, jockey Jim Crowley has been discharged from St George's Hospital, Tooting, to return home with his family," read a statement.
"Freddie Tylicki, also involved in the incident, is in intensive care in a stable condition. He is conscious and there will be a further update tomorrow once more is known."
Drowne and Durcan were able to walk back to the weighing room following the incident, while it was reported that the four horses were not seriously injured.
