Leading Brisbane apprentice Baylee Nothdurft will seek an internal review of a decision to suspend him for a month for causing interference resulting in a fall.

Stewards suspended Nothdurft after he was found guilty of careless riding in an incident that led to Tegan Harrison falling at Doomben on October 7.

Jockeys Michael Cahill, Brad Stewart and Jake Bayliss also fell in the backwash.

Harrison was the most seriously injured with damage to her sternum, ribs and vertebrae.

She also required surgery on a collarbone but hopes to be back riding by February.

Nothdurft argued that his shift in on Harrison's mount had been minimal but stewards disagreed.

He is currently serving a 12-day suspension for careless riding at Doomben last Saturday.

Nothdurft's master Tony Gollan confirmed Nothdurft would appeal the one-month ban.

The matter now goes to an internal review and if that is unsuccessful, Nothdurft can further appeal to the Queensland Civil and Administrative Tribunal.

Nothdurft is currently second on the metropolitan senior riders' premiership with Jim Byrne leading.
