Emerging apprentice Nathan Berry's momentum has been stalled after he suffered a suspected shoulder injury in a fall at Canterbury on Thursday night.

Berry's mount Trinitarian came down rounding the home turn and the 18-year-old was tossed to the ground.

His twin brother Tommy, also an apprentice jockey, rushed to the scene and accompanied him to the Royal Prince Alfred Hospital.

Chief steward Ray Murrihy said it appeared Berry had injured his shoulder or collarbone in the fall.

"Nathan has been taken to RPA for x-rays and it appears to be either his shoulder or collarbone," Murrihy said.

Berry has ridden 13 winners in the Sydney metropolitan area this season.

An interested spectator at the Canterbury meeting was leading senior rider Peter Robl who is recovering from a serious neck injury.

Robl fractured a vertebra in a three-horse fall on December 10 and was in a neck brace until this week.

Robl said he would have another scan on February 10 and hoped to be back riding in races by February 28.

"It's such a relief to have the neck brace off," he said.

"Now it's just a question of getting fit with physio and exercise.

"I was 59 kilos earlier this week and now I'm at 57 so it shouldn't take too long."

Robl is the retained rider for Patinack Farm racing concern which had a winner at Canterbury with Subtle Cove ridden by Rod Quinn.
