Champion jockey Anthony Delpech will undergo surgery today after being diagnosed with a disc herniation and a damaged spinal cord after being dislodged from his horse in the SA Classic at Turffontein on Saturday according to his agent Deez Dayanand.

Delpech was riding the favourite Majestic Mambo who was travelling smoothly until clipping heels at about the 400m mark. As his mount stumbled, Delpech was dislodged and landed awkwardly.
