Arsenal striker Danny Welbeck has been ruled out for a month with a groin injury, according to the Telegraph.
The England international suffered the injury in the last quarter of the Gunners' goalless draw with Chelsea on Sunday.
The report claims that following an initial scan on Monday, Arsenal fear that Welbeck will be on the sidelines for a month.
The 26-year-old has scored three league goals for the North London club this season.
