Jockey Steven Pateman has been taken to hospital with concussion after a fall in a maiden hurdle at Warrnambool.
Pateman was riding the $2.50 favourite Sir Issac Newton who was in front when he fell at the final jump in Tuesday's Carlton Draught Maiden Hurdle (3200m).

The jockey was ruled out of the remainder of Tuesday's all-jumps program on the opening day of the two-day carnival and was taken to the Warrnambool hospital for further tests and observation.
Pateman was to ride Zed Em for trainer Patrick Payne in the day's feature, the Grand Annual Steeplechase (5500m) and has been replaced by Aaron Lynch.
Sir Isaac Newton suffered a fractured shoulder in the fall and was euthanised.
The eight-year-old gelding is the second horse in as many years to be put down at the famous jumps carnival, after Blues Breaker was euthanised after a steeplechase fall in 2019.
“He travelled really well and he was going to win but he didn’t measure the last properly and came down very hard,” trainer Ciaron Maher said.
Veteran trainer optimistic ahead of Wangoom Handicap
Trainer Danny O'Brien is confident Order Of Command is in the right form and will get the right conditions to give the Wangoom Handicap at Warrnambool a shake.
The trainer says his only query is the 62kg top weight the consistent sprinter will carry in Wednesday's Listed 1200m race.
Order Of Command has been aimed at the Wangoom and showed he was on target when he returned from a spell in style with a convincing win last month over 1200m on a soft track at Caulfield carrying 60kg.
The Warrnambool track was rated in the soft range on Tuesday which is what O'Brien had been banking on when he set Order Of Command for the race.
Order Of Command has seven wins and six placings from his 20 starts, while in six attempts on soft-rated tracks he has notched four wins, a second and a fourth.
"You can pretty much rely on Warrnambool being rain-affected and we were looking to run him in a nice race on rain-affected ground," O'Brien said.
"The first-up run was a bonus. We got the rain that day as well.
"He prefers that soft six or soft seven which it should be for him tomorrow.
"The question is whether he can carry the 62 kilos."
