Manchester United are worried they could lose Romelu Lukaku for the remainder of the season.

United are sixth on the table and have matches against Huddersfield and Cardiff to close out the campaign.

ESPN claim Lukaku is in doubt for Saturday's visit to the Terriers due to a hamstring injury.

The Belgian striker underwent a scan on Tuesday and could be left out for the rest of the season.

On a positive note for United, Jesse Lingard will be available for both matches.
