Manchester United boss Louis van Gaal has confirmed that Wayne Rooney has a knee injury.
Eyebrows were raised when Rooney did not board his team's flight to Denmark ahead of Thursday's Europa League last-32 clash against FC Midtjylland.
A report on Wednesday afternoon claimed that the England captain had suffered knee ligament damage and would be on the sidelines for the next two months.
Van Gaal has confirmed that his skipper will miss Thursday's game with a "knee problem", but gave no indication as to how long the 30-year-old would be on the sidelines.
"We have 13 players injured and Wayne Rooney is one of them. You can never say [how long he could be out for]. He has a knee problem so we must wait and see," Van Gaal told reporters.
Van Gaal also confirmed that Cameron Borthwick-Jackson has not made the trip due to illness.
