Lyle Hewitson under observation in hospital (Picture Supplied).

Lyle Hewiton had a terrible fall at Happy Valley on Wednesday night, but an update on his condition and that of the otther two jockeys involved was positive considering the severity of the incident.

However, he might be unable to make the Gold Cup meeting at the end of the South African season, which he had intended to ride in.

Hewitson’s mount came down after breaking down and it appears two other horses were brought down.

It was near the end of the fifth race.

Karis Teetan managed to walk away from the incident, but was taken to hospital for observation together with Hewitson and Jerry Chau.

A report on their condition later stated:

Imaging of Lyle Hewitson has identified fractures of his right wrist and suspected ankle, with no other identified injuries and he remains under observation.

Imaging of Jerry Chau has not identified any injuries and he remains under observation.

Karis Teetan has no identified serious injuries and is undergoing precautionary imaging.

Both Hewitson and Chau rode winners before their falls, with Chau coming from behind midfield to strike on My Day My Way in the second section of the Class Four Hereford Handicap.

Hewitson got on the scoresheet for a relieved David Hayes, who snapped a 39-runner losing sequence when Amazing Run lived up to his name to win the second section of the Lancashire Handicap.

With the Hong Kong Season coming to an end on 16 July, Hewitson will not see action again and will end on 28 winners and gross stakes of HK$51 805 725.
