Taking charge of his second North End game of the season this weekend is match official David Webb.
The Lancashire referee took the whistle for the August trip to Pride Park and is now in his 11th season on the EFL lists and is taking charge of his 14th game of the season, having so far issued 37 cautions and one red card.
Before the Derby game it was early 2016 since we last saw his running a North End game. That season he refereed North End's 2-0 home win over Peterborough United.
Since then he has refereed PNE on ten occasions, some of the most memorable games including the FA Cup win at Wycombe Wanderers, when Kevin Davies scored a stunning strike from 35 yards, and a 3-2 home win over Crewe Alexandra in 2011.
This is his first Birmingham City game of the season and the first game where he has been in the middle at St Andrews in his long refereeing career.
At St Andrews he will be joined by Mark Russell and Lee Venamore, who will run the lines, whilst the fourth official is fellow Select Group Two referee Darren England.
