The 31 year old was promoted to the Football League national list at the start of the 2011-12 season and has refereed three Royals games since—games we haven't lost under his control.
The most recent of those was the entertaining 3-3 draw against Wolves earlier this season.
Overall in 2014-15, Adcock has officiated 27 games, giving 94 yellow cards and nine red cards, averaging a fairly high 3.8 cards per game.
The Nottinghamshire-born ref sent off both Ross McCormack and Leon Barnett in Wigan's 3-3 draw with Fulham in November.
Adcock also gave two penalties in that game, contributing to a total of five spot-kicks he has awarded this campaign (four have been scored).
His 'other' job is a PE teacher at a school in Greater London, where he says he is grateful that the school are an "understanding employer" and "believe that having a teacher who referees in his spare time helps to promote respect."
Which players could be in detention by 10pm on Tuesday evening then? Only time will tell.
