Bournemouth defender Tyrone Mings denied that he intentionally stamped on Zlatan Ibrahimovic's head in their 1-1 draw at Old Trafford on Saturday.
Marcos Rojo's opening goal was cancelled out by Josh King's penalty, before Mings and Ibrahimovic clashed prior to half-time.
Mings was seen to stamp on Ibrahimovic's head before the striker then caught his opponent with his elbow.
Neither player was dismissed by referee Kevin Friend although Andrew Surman did receive a second yellow card after he shoved Ibrahimovic.
A Football Association source told ESPN FC that disciplinary chiefs will wait for Friend's match report before deciding whether to take any action against either Ibrahimovic or Mings.
When asked whether he deliberately stamped on Ibrahimovic's head, Mings told Sky Sports: "Not at all. I would never do that. That's not in my game. Hard and fair is how I like to tackle but off the ball stuff like that isn't in my game.
"He [Ibrahimovic] is who he is, he's a good player, he's a physical player. I knew what sort of battle I was going to be in for coming here. And that's what we had all day, it was a battle.
"There was maybe an elbow when the ball came in after, I didn't see it, I felt it. But what happened after that with Surman getting sent off, I didn't see it."
Ibrahimovic also saw a second-half penalty saved by goalkeeper Artur Boruc as United failed to climb the table and remain sixth.
United captain Wayne Rooney said after the match that he expected Mings to face retrospective action for the incident
He told Sky: "I don't think he [the referee] has seen Mings stamp on Zlatan's head -- I was right there. It's wrong.
"Everyone likes to go in for tackle in the game but to try and stamp on a player's head is wrong -- there's no place for it. I'm sure there will be punishment."
Jose Mourinho refused to be drawn on the incident after the match,
The United manager said: "I don't like to speak after matches. The referee was there; if you ask me if I'm going to be happy if Mings gets a four or five-game ban, I really don't care about it. He knows what he did better than anyone, better than the referee the intention or the emotion of the moment."
