Whites head coach Marcelo Bielsa could be allowed an increased match-day squad of 20 players with five substitutions permitted meaning an extra two slots for two more players on the bench.
United's next game as far as the fixture list was concerned is Cardiff City away.
13. Gaetano Berardi
Ever reliable, right back or centre-back Berardi came into the side for the injured Phillips against Huddersfield but would seem likely to take a place back on the enlarged bench. Picture by Bruce Rollinson. | jpimedia
14. Pascal Struijk
If Berardi is back among the subs it's probably a toss up between Struijk and Oliver Casey as another centre-back option in the 20. Leif Davis and Alfie McCalmont are also knocking on the door for bench spots. Picture by Bruce Rollinson. | jpimedia

16. Jamie Shackleton
The 20-year-old looks a banker for the bench given not just his talent and energy levels but also his ability to play in many different positions. Picture by YPN. | jpimedia
17. Gjanni Alioski
Another that has been kept out of the side by Dallas, as well as Costa and Harrison given Alioski's versatility as a full-back or a winger but a fine option from the bench. Photo by Simon Hulme. | jpimedia
18. Jordan Stevens
In terms of another attacking option, Ian Poveda, Mateusz Bogusz, Robbie Gotts and striker Ryan Edmondson are among the leading contenders but Stevens regularly makes the bench as it is so ought to make the 20. Photo by Matt King/Getty Images | Getty
