Manchester United's defender Luke Shaw (28) is poised to be sidelined for several weeks due to a muscle injury, as confirmed by the Premier League club on Thursday.

While the extent of the problem is still under evaluation, the left-back's absence has already been confirmed for the "upcoming matches."

Shaw, a consistent presence in manager Erik ten Hag's lineup, initiated United's participation in the first two league matches—securing a 1-0 victory against Wolverhampton Wanderers and experiencing a 2-0 loss to Tottenham Hotspur.

As United gears up to face Nottingham Forest on Saturday and subsequently travels to take on last year's runners-up Arsenal, Shaw's availability is doubtful.

These matches will be followed by an international break.

Furthermore, midfielder Mason Mount's participation in both games has already been ruled out due to an injury sustained during their 2-0 defeat against Spurs.

Additionally, the backup left-back Tyrell Malacia remains unavailable due to an injury sustained in the previous season.
