Oliver Langford will take charge of Derby County's 2017/18 Sky Bet Championship fixture at Ipswich Town on Saturday afternoon (3pm kick-off).
Langford has overseen 23 games so far this season, producing a total of 76 yellow cards and three reds.
His last Derby game was the season-opener at Sunderland back in August, which ended in a 1-1 draw, while he also oversaw the Rams' 3-0 home victory against Rotherham United at Pride Park Stadium last season.
Langford will be assisted by Lee Venamore and David Avent on the lines, whilst Andy Woolmer has been appointed as the Fourth Official.
