The AFL Appeals Board have upheld Saint Ben Long's one-match ban on Wednesday night.

He was charged for a dangerous bump on Bulldog Jackson Macrae in Saturday’s elimination final clash at the Gabba.

The MRO graded the incident as medium impact with careless conduct and high contact, resulting in a one-match suspension, with the Saints challenging the charge at the Tribunal.

St Kilda’s attempts to have the ban overturned on Monday night were unsuccessful, with the club getting the same result at the AFL Appeals Board.

It means Long will miss Friday night’s semi-final clash against Richmond.

His suspension is a major blow for St Kilda, with Patrick Ryder (hamstring) and Jake Carlisle (personal) also being forced omissions this week.
