Lyle Hewitson, Jerry Chau Chun-lok and Karis Teetan were taken to hospital after a horror fall during the Class Three St George’s Challenge Cup (1,000m) at Happy Valley on Wednesday night.

Hewitson was speared into the turf when $3 favourite Seasons Wit came down around 75m from the line after fracturing his left fore fetlock, with the South African jockey suffering a fractured wrist and a suspected fractured ankle.

Seasons Wit fell in front of Eternal Fortune under Chau and Teetan’s mount, Watch This One, and while both gallopers managed to keep their feet, Chau and Teetan also fell.

In a club statement, it was reported that Hewitson and Chau were conscious following the incident and taken to hospital for further medical examination.

Teetan limped away from the pile-up and was later stood down from his remaining rides before going to hospital for precautionary scans.

The club confirmed imaging of Chau “has not identified any injuries” and Teetan “has no identified serious injuries”. Hewitson and Chau remained under observation overnight.

The Jamie Richards-trained Seasons Wit could not be saved and was humanely euthanised, while the Pierre Ng Pang-chi-trained Watch This One and Danny Shum Chap-shing’s Eternal Fortune were taken to the equine hospital for further examination.

The race was ultimately won by the Tony Cruz-trained Superb Capitalist, who pinched the prize from Youthful Spirits in the final bounds after a brilliant ride by jockey Matthew Chadwick.

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 (1,200m).

It was a first win at the seventh attempt for the Shum-trained four-year-old, who powered home down the outside to overhaul New Power in the last few strides for a most unlikely success.

“He ran a tremendous race. I knew coming to the outside would be hard but we were very lucky,” Shum said.

“The last 20m, he was very strong. I think he can win in Class Three as well. I’ll give him a break now and wait for next season.”

Things got even better for Shum later on the card when Wrote A New Page kept up a relentless gallop to go from pillar to post in section one of the Class Four Lancashire Handicap (1,650m).

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.

The Zoustar galloper won on his seasonal return back in September but had to wait nine runs to get back on the scoresheet, charging home from the back of the pack to win a shade cosily.

“He’s had a really unlucky year with bad barriers – tonight included – but Hewitson rode a great race and he won like a good horse, so we’re very happy,” said Hayes.

There was also a double on the card for trainer Michael Chang Chun-wai, who scooped the first race – the Class Five Chester Handicap (1,200m) – with the Derek Leung Ka-chun-ridden Woodfire Champ.

After New Power was cruelly claimed by My Day My Way late on in the next race, Chang was quickly back in the winners’ enclosure when Amazing Victory overhauled $3.6 favourite Fun Elite in the third section of the Hereford Handicap.

In the race for the Tony Cruz Award for the leading local jockey, Matthew Chadwick slashed Matthew Poon Ming-fai’s lead down to two with a double of his own, spearheaded by Another Zonda’s gutsy win in the Class Three Renfrew Handicap (1,650m).
