Theo Walcott has dislocated his shoulder while training with England ahead of Wednesday’s friendly against Germany in Berlin.
Theo was taken to hospital where the shoulder was put back into place.
A decision will be taken on Wednesday morning over when the 19-year-old will return to England.
And his Arsenal team- mate Robin Van Persie is close to agreeing a four-year extension taking him to 2013.
The Gunners are desperate to tie England star Walcott (right), 19, to a long-term deal.
He has 18 months left on his current deal but such is his magnificent form for club and country, boss Arsene Wenger is ready to double his wages to £60,000-a-week.
Walcott, a £12m signing from Southampton in January 2006, is happy at the Emirates despite Chelsea and Real Madrid interest.
Arsenal produced a great display to see off the current premiership Champions at the Emirates Stadium.
Two goals from Nasri set Arsenal on their way to the win with a late strike by United’s Rafael to make it finish 2-1
Arsene Wenger says Arsenal duo Emmanuel Adebayor and Theo Walcott suffered ‘very bad injuries’ in the 2-1 defeat at Stoke City.
Adebayor was replaced by Carlos Vela after 73 minutes of the loss at the Britannia Stadium after picking up a couple of knocks.
Walcott had only been introduced as a second-half substitute, but was stretchered off with a suspected shoulder injury in the dying embers of the game.
Though Wenger did not confirm the severity of the two players’ injuries, the Gunners boss hinted that Adebayor and Walcott could be out for several weeks.
