Matteo Darmian has joined the list of  Manchester United walking wounded after suffering a shoulder injury in the first half of their Premier League clash against Sunderland.

Darmian left the pitch with his arm in a makeshift sling after he collided with Wahbi Khazri by the right-hand corner towards the end of the first half.

It is yet another injury to a United full-back, with Luke Shaw, Antonio Valencia, Ashley Young and Marcos Rojo recovering from long-term injuries, while Phil Jones and Guillermo Varela broke down when playing for the Under-21s on Monday night.

Darmian was replaced by Scotland Under-21 international Donald Love, making his debut for the club, as he became the latest in a string of youngsters to be promoted to the senior side this season.

New signing Khazri had given Sunderland the lead after three minutes from a free-kick before Anthony Martial levelled the scores at the 39-minute mark. It was 1-1 at half-time.
