Manchester United striker Zlatan Ibrahimovic says he will "come back even stronger" after his injury.
The 35-year-old was injured during last week's Europa League quarter-final second-leg win over Anderlecht. It was later confirmed he has suffered cruciate knee-ligament damage.
With 28 goals Ibrahimovic is United's top scorer this season but it looks unlikely that he will be able to return before the campaign finishes.
The Swede took to Instagram, where he wrote: "I will be out for a while. Giving up is not an option. I will go through this like everything else and come back even stronger. So far I played with one leg so it shouldn't be any problem. One thing is for sure, I decide when it's time to stop and nothing else."
