It shouldn't matter:

Following the postponed Sky Bet League One encounter with Brentford, and given the continued adverse weather conditions, Sheffield United has commissioned a full pitch covering solution from Northamptonshire-based company Sports and Stadia with the intent of ensuring Sunday’s game against Nottingham Forest will go ahead.
This is the same protective covering that was used effectively ahead of the Blades’ fourth round FA Cup tie against Fulham.
Head of Operations at United, Dave McCarthy, explains: “Like the majority of Football League clubs, we do not own covers that protect the whole surface, and so the Club has acted quickly to make sure that the extreme wet weather does not get the better of us again.
"Both United and Forest have agreed to share the significant cost of hiring the system, in order to make sure the game can be played as scheduled.
"The Bramall Lane playing surface has now been fully covered with the pitch protection system to avoid from any further saturation from the elements."
