Luke Shaw could reportedly miss the next three weeks of the season with the groin problem that he aggravated in Manchester United's 3-1 defeat to Watford in the Premier League at the weekend.
The England international, who missed the majority of last season with a broken leg, has started all five of Man United's league matches this season.
However, according to The Telegraph, the left-back will undergo a scan on his troublesome groin on Tuesday morning and the early indications are that he will miss at least the rest of the month.
Shaw came in for criticism from head coach Jose Mourinho following the Watford defeat, with the left-back blamed for not tracking Nordin Amrabat in the build-up to the home side's second goal.
Man United will attempt to bounce back from three straight defeats when they travel to Northampton Town in the third round of the League Cup on Wednesday night.
