Manchester United defender Lisandro Martinez will miss the next two months with injury.
The club has announced the Argentina international suffered knee ligament damage during Sunday's win against West Ham.
Lisandro will not require surgery, but will be sidelined "for eight weeks", United stated.
He missed the latter stages of last season after fracturing a metatarsal in April.
The defender then suffered "an aggravation" to the injury at the beginning of this term.
