Nottinghamshire's Russell Booth gave a consummate performance during Leeds' 4-1 victory at Scunthorpe United earlier in the season, booking one player.
Tomorrow's game is his second involving the Elland Road club in little over a month.
It is rare for the Nottinghamshire official to issue more than two yellow cards in a single fixture and he has shown his red only once this season, in a League One game between Hartlepool United and Brighton.
Leeds have no contentious history with the official.
