Occasionally, top referees are required to take charge of matches outside the top flight - and now it is time for Rennie to visit Shrewsbury.
He will be in the middle for the game with high-flying Macclesfield on March 12.
Rennie has had a controversial career, angering many managers and prompting Kevin Keegan to say:"I never talk about Uriah Rennie except to say I don't like him as a referee - never have, never will, end of story."
And Town fans could have similar opinions after Rennie dismissed two players in Towns 4-0 FA Cup defeat at Grimsby in 1997.
