Maguire, who had appeared in every league minute in 71 games before United’s 3-1 win at Aston Villa, was forced to leave Villa Park in the 78th minute with an ankle injury following an entanglement with Anwar El Ghazi.
Due to the rapid turnaround in games United manager Ole Gunnar Solskjaer has already ruled Maguire out for Leicester’s visit and the club captain will do a scan on Monday to determine the extent of his injury.
“The players are learning, developing, the squad as a whole is improving,” Solskjaer said. “You went to the stadium, you hear the spirit, the camaraderie, they support each other, there is a competition for places. Very glad we’ve done this twice now. “
“We have a final to look forward to. Hopefully it will be with Harry Maguire, I don’t know. We have to check it out. It might take a few weeks, it might take a few days, who knows.
“I hope he won’t be too bad but I’m not a doctor and we have to check him and scan him tomorrow. It was his ankle, his leg, I think the boy landed on him, so he twisted his ankle and received a hit.
“Harry has been excellent and it’s almost unheard of the minutes he played without missing out.” His physical form is very good, he is sturdy but today it looked like the boy had landed on him and he twisted his ankle, so this is something you can’t really defend yourself against, unfortunately, he had to withdraw.
“I don’t know how bad it is. Maybe he’s available for Thursday, I don’t know, I’ll tell you more on Tuesday night when I see you all. “
Eric Bailly replaced Maguire against Villa and is expected to line up on Tuesday.
