However, the game is still subject to change, depending on what happens in the fifth round of the Emirates FA Cup.
Sheffield United are at Reading on 3 March, while United are away to Derby County a couple of days later and, if either one or both of the Premier League clubs progress, it will result in the league fixture being postponed.
The alteration in the Sheffield United fixture is due to the Europa League round-of-16 ties with LASK being slotted into the schedule.
United are in Linz for the first leg on Thursday 12 March, with kick-off at 17:55 GMT, followed by the return at Old Trafford a week later (20:00 GMT).
