Manchester United striker Danny Welbeck has been ruled out for four to five weeks with a hamstring injury and will miss the upcoming England under-21 internationals.
The 20-year-old netted during United’s 8-2 victory over Arsenal yesterday, but pulled up with a hamstring strain later in the first-half.
"Danny complained of a tight hamstring before he actually pulled it and we couldn't get Hernandez on quick enough," United boss Sir Alex Ferguson told BBC Sport.
"It is a shame for Danny but it will be around four to five weeks."
Welbeck was called up to the England Under-21 squad along with United teammate Phil Jones last week for matches against Azerbaijan and Israel in September.
