Manchester United have confirmed that Zlatan Ibrahimovic and Marcos Rojo have both suffered "significant" knee ligament injuries.
Ibrahimovic and Rojo both sustained their respective injuries during United's 2-1 Europa League quarterfinal second-leg win over Anderlecht on Thursday, with the former landing awkwardly and the latter colliding with an opponent.
United said in a statement on Saturday evening that both players would need to undergo "specialist opinions" before knowing the full extent of their injuries and how long the pair would be out for.
