Manchester United star Joshua Zirkzee could miss the rest of the season with a hamstring injury in a huge blow for Ruben Amorim.
Zirkzee limped off in the second half of the 4-1 defeat at Newcastle on Sunday and is likely to be ruled out for several weeks.
Amorim looked visibly concerned as the 23-year-old Dutch international left the field at St James' Park and there are now doubts that he will feature again this season.
His injury came just days before United face Lyon in the second leg of their Europa League quarter-final, a game which will define the Red Devils' campaign.
