The Gunners boss believes the forward could miss the international break after straining his buttock muscles during Saturday afternoon's 3-3 draw with FulhamArsenal boss Arsene Wenger has revealed that Theo Walcott is a doubt for England's upcoming friendly clash with Sweden after picking up a buttock muscle injury during Saturday's draw with Fulham.
The 23-year-old was handed his first Premier League start of the season against the Cottagers and had a hand in two of his side's three goals.
But, after the winger was withdrawn with six minutes remaining, Wenger has admitted he has sustained a blow which will need to be assessed.
"Walcott has a glute muscle problem," the Frenchman told reporters.
"We nearly took him off at half-time, he nearly went down, but we left him on and on.
"In the end, it got worse and worse. At the moment, he is limping so I do not know whether he will be able to join the national team or not."
Walcott has been scoring freely so far this season, bagging seven goals so far, but is refusing to pen a new Gunners contract.
