Manchester United midfielder Ander Herrera is doubtful for their FA Cup tie at Huddersfield Town.
The 28-year-old Spaniard has picked up an injury to his left thigh and could be out for a few weeks as he waits to see how it responds to treatment.
Jose Mourinho confirmed Herrera had picked up a muscle knock, as has Marcus Rashford, following Sunday's defeat by Newcastle United.
Herrera, who was named the club's player of the year last season, has been pushed to the fringes by the arrival of Nemanja Matic this campaign but was being considered for a recall to a starting place as United's midfield struggles for form.
