Manchester United defender Lisandro Martinez could have been in VAR trouble against Leeds United.
The Red Devils centre-half appeared to catch Leeds' Patrick Bamford in the face with his boot during a coming together.
Both players had gone to ground for a challenge, when Martinez's foot appeared to hit Bamford a couple of times as he gathered himself.
Martinez has been impressive for United this season, slotting in alongside Raphael Varane.
He was recently praised by United legend Rio Ferdinand as one of the best defenders in the Premier League.
The Red Devils take on Leeds again in the league on Sunday.
