The 26-year-old Rashford had a stellar 2022/23 campaign, scoring 30 goals in all competitions and went on to be named United's player of the year, but the England international has only netted eight times this season.

McTominay, meanwhile, has 10 goals across all competitions this season.

The duo picked up their respective injuries during Sunday's FA Cup semi-final against Championship side Coventry City, which United won on penalties after surrendering a 3-0 lead at Wembley.

"We had a problem with (Alejandro) Garnacho, that's why we took him off during the game, but I think he will be fine," Ten Hag told reporters.

"Scott we have to assess today, really doubtful. Marcus is also doubtful, and there was also an issue with Bruno (Fernandes) with the hand but I think he can make it.

"We have some doubts going into the game tomorrow."

United are already facing a defensive crisis due to injuries to Lisandro Martinez, Raphael Varane, Victor Lindelof, Jonny Evans, Luke Shaw and Tyrell Malacia.

United are seventh in the league standings with 50 points, 16 behind fourth-placed Aston Villa with six games to go. Sheffield United are fighting relegation and sit bottom, having won just three of their 33 matches.
