Paris St Germain have confirmed Neymar will be out for up to 10 weeks with a foot injury, ruling him out of both legs of their Champions League last-16 tie with Manchester United.
The 26-year-old Brazilian, the world's most expensive player, suffered the injury against Strasbourg in the French League Cup last week.
PSG travel to Old Trafford on February 12, with the return leg in France on March 6.
A statement on the PSG website said: "On Tuesday evening Paris St Germain gathered together a group of world-renowned medical experts at the Ooredoo Training Centre to carry out a thorough review of the injury to Neymar Jr's right foot, sustained against Strasbourg in the Coupe de France round-of-16 match on January 23.
