Khumalo comes off his horse on the way to the start of Race 1 at Greyville.
Jockey S’manga Khumalo was taken to hospital for observation after his mount in Race 1 at Greyville on Friday evening, Bling A Ding Ding, dumped him on the way to start.
Khumalo was taken off the ride and was replaced by Tristan Godden.
Reports from Greyville indicate Khumalo appeared to be fine but the on-course medics felt he needed to be checked out fully and have X-rays to ensure there were no latent issues.
At this stage it is unsure whether Khumalo will be able to ride at Turffontein on Saturday.
The worst news for Khumalo is that Bling A Ding Ding not only ran in Race 1 but went on to win under Godden.
