Blues have already had the pleasure of the Hertfordshire-based official refereeing four of their games this season whilst Graham Poll has yet to take charge of a Boro fixture during this campaign.
The last Blues game that Graham Poll refereed was in our 2-0 away defeat to Charlton on 14th January. No Blues players were booked at the Valley that day.
Prior to the Charlton game Graham Poll had taken charge of our our 2-2 League Cup 4th Round victory at Millwall back on 29th November 2005. Nicky Butt, Julian Gray and Matthew Upson were all booked that night.
He also took charge of the home defeat to Aston Villa in October 2005 when Damien Johnson and Mikael Forssell both picked up a yellow card and the away win against West Brom in August 2005 when Matthew Upson, Jiri Jarosik and Jamie Clapham were all booked.
In total Graham Poll has taken charge of 21 Premier League games so far this season in which he has handed out 82 yellow cards and 4 reds.
Mr M Tingey and Mr G Turner will be Graham Poll's assistants at the Riverside on Saturday afternoon.
