Jockey Tom Sadler will have surgery after suffering a broken leg in a freak accident in a jumps race in Victoria.

Sadler was kicked as he and his horse went past a fallen horse in a steeplechase at Casterton on Sunday.

The jockey suffered a fractured tibia and was scheduled for surgery in Melbourne on Monday.

“Unfortunately yesterday i broke my leg from the hoof of a fallen horse. Thanks to all for texts and calls, heading to Epworth soon for surgery. Trying to explain how i broke my leg without having a fall is as painful as the break, see ya next season” Sadler said on Twitter on Monday morning.
