Victorian trainers Mark Thomas and Shannon Hope face conduct charges over two separate altercations with each other.

Thomas has been charged for an incident on October 9 last year with stewards alleging he went to the Seymour stables of Lee and Shannon Hope and engaged in a verbal altercation with the latter while in possession of a firearm.

Stewards allege Hope engaged in a verbal altercation with Thomas at trackwork at Seymour on February 6 before striking him on the left side of his face.

The Racing Appeals and Disciplinary Board will hear the improper conduct charges brought against the two on a date to be determined.
