Arsenal winger Alex Oxlade-Chamberlain will reportedly miss Saturday's trip to Manchester United through injury.
The 19-year-old had been expected to feature in the match at Old Trafford after recovering from a hip problem.
However, a groin injury that he is understood to have sustained in training could now see the England international ruled out for the Gunners, according to Goal.com.
Oxlade-Chamberlain has scored one goal in seven appearances for Arsenal so far this season.
