Manchester United may need to hasten their pursuit of another centre-back after the injury to their new summer signing.
Leny Yoro joined Man United from LOSC Lille for £52 million this summer.
He was named in the starting XI in a 2-1 defeat to Arsenal on Saturday. His evening was cut short due to an injury and he was substituted in the 35th minute.
The Times reported that the injury appeared more severe than Rasmus Hojlund’s. He was taken off in the 16th minute with an apparent muscle injury.
