He will miss Wednesday's EFL Cup tie at Northampton and is 50-50 for Saturday's Premier League visit of Leicester.

Shaw, 21, played 85 minutes of Sunday's 3-1 defeat by Watford, after which he was criticised by boss Jose Mourinho.

He said Shaw, who returned last month after breaking his leg a year ago, was too far from Nordin Amrabat in the build-up to Watford's second goal.

Shaw has started all five of United's Premier League games so far.

The Red Devils have lost their past three matches.
