Manchester United look set to be without Raphael Varane for this month's Premier League meeting with Liverpool.
The central defender sustained a groin injury during Sunday's UEFA Nations League final over Spain in Milan.
Varane was replaced by Bayern Munich's Dayot Upamecano two-minutes before half-time at the San Siro.
United confirmed on Tuesday that their €41million summer signing will be out for "a few weeks". It adds to their defensive worries, with Harry Maguire out for an undetermined period with an ankle injury.
That could open the door for Phil Jones to make a first United appearance in 19-months.
Varane started United's five most recent Premier League games, and was a key member of their side for the Champions League meetings with Young Boys and Villareal.
