The Red Devils have picked up several untimely injuries this campaign and they have suffered another setback ahead of the Cherries game.
Speaking in his pre-match presser, manager Ruben Amorim revealed that Diogo Dalot picked up a calf injury in training this week.
The Portuguese will be ruled out for the coming matches and Amorim said that there is a possibility that he could be sidelined for the season.
The news is a huge blow for the Red Devils, considering Dalot has been one of the in-form players for the club in the second half of the campaign.
He was exceptional in the second leg of the Europa League quarter-final versus Lyon where United secured a superb 5-4 comeback win.
Dalot has been an ever-present figure with sublime fitness levels and he will be a huge miss for the remainder of the ongoing campaign.
