Manchester United boss Jose Mourinho has admitted that his club are "not sure" whether Eric Bailly is facing another period on the sidelines following Wednesday's 2-1 win at Crystal Palace.
Bailly, who has only just returned from a long lay-off, picked up a knee problem in the early stages of the Premier League clash at Selhurst Park and was eventually replaced by Matteo Darmian at the start of the second period.
Mourinho has confirmed that the damage occurred to a different knee than the previous injury, but the Portuguese refused to place a timescale on the Ivorian's absence.
"We are not sure about Bailly. It is not the same knee. He has a problem, but we do not know the dimensions. He showed amazing character before having to leave the field," Mourinho told BT Sport.
Experienced forward Zlatan Ibrahimovic netted an 88th-minute winner at Palace as Man United made it back-to-back Premier League victories for the first time since August.
