Manchester United boss Erik ten Hag admits he has injury concerns for Christian Eriksen and Rasmus Hojlund.
Both players were forced off during the win against Luton.
"In this moment, I can't tell anything about it because I don't know," Ten Hag said of Hojlund's issue. "We do an assessment and we have to wait 24 hours for the conclusion. So we'll give the medical team 24 hours to see what the problem is, if there is a problem.
"You don't want to miss any player. There's also Christian Eriksen. That is our season at this moment we have so many injuries. But, therefore, you have a squad. We have talked about it many times. But, of course, the routine levels are dropping down, the routine levels in the team, in the way of playing. But, hopefully, players are coming back and those new injuries are not too bad."
Asked about Eriksen, he replied: "He slipped but it's the same we have to do the assessment, set the diagnosis, set the conclusion and then we'll know where we are."
On if the pair would have to pull out of the Denmark squad, Ten Hag added, "It could be.
"But I can't give now a good assessment. We have to wait and then see what the conclusion is."
