Premier Sydney jockey Hugh Bowman has been taken to hospital with suspected concussion after falling from leading Golden Slipper contender Performer at Randwick.
Bowman suffered cuts and abrasions in the incident which happened in the straight during Saturday's Todman Stakes.
Chief steward Marc Van Gestel said Bowman had briefly lost consciousness while the Chris Waller-trained Performer appeared to escape any injury.
"Hugh is obviously sore and sorry and was unconscious for a short time," Van Gestel said.
"It doesn't appear he has suffered any breaks but he will have X-rays to make sure."
