FA Cup: Sebastian Stockbridge referees Leyton Orient v Carlisle United

Sebastian Stockbridge has been appointed referee for the first round tie in east London.

The official encountered the Blues very recently - in their most memorable game of the season so far.

He was in charge of United's 3-1 win at Bolton Wanderers, a game in which he awarded the Cumbrians two penalties.

Before that, Stockbridge was in the middle for April's contentious 3-2 home defeat to Salford City when he sent off Jon Mellish for shoving Elliot Watt.

He also awarded the Cumbrians a spot-kick that day.

Prior meetings with Stockbridge include last season's 2-0 defeat at Barrow in the EFL Trophy - a game held up for a spell after a home fan threw a firework into United's penalty area.

This weekend will be a rare southern game when Stockbridge will take charge of a Carlisle game.

Some 17 of his 23 encounters with the Blues since 2013 have come at Brunton Park, with the away games at Morecambe, Harrogate, Bolton, Barrow (twice) and Mansfield Town.

His assistants at Brisbane Road on Saturday will be Garry Maskell and Ryan Head, with Harry Wager the fourth official.
