Manchester United's defensive injury woes have worsened with the news that Marcos Rojo dislocated his shoulder in training on Wednesday.
Sky Sports is reporting the fullback dislocated the same shoulder he injured against Machester City last season.
The severity of the new knock is unknown, but Rojo spent four weeks on the sidelines after the City incident even though it didn't need surgery.
It is a further knock to the embattled backline at the Red Devils, who is already without Luke Shaw and Antonio Valencia.
Rojo began the season in manager Louis van Gaal's bad books after missing the club's pre-season tour to America, but his services were needed due to their current injury problems and has impressed at left back recently.
Van Gaal has some thinking to do regarding who will line up in defence against West Ham United on Saturday.
