"Patrick Dorgu is expected to be out for around 10 weeks after scans revealed a hamstring injury," The Athletic reported .
The 21-year-old suffered the injury during the Red Devils' 3-2 win against Arsenal last Sunday.
Dorgu suffered a hamstring problem while chasing a long ball in the second half of the match.
In fact, he performed brilliantly in the match by scoring a goal with a half-volley kick from outside the penalty box.
Until now, Manchester United is still conducting further examinations to determine the severity of the injury.
