Neymar will miss the first leg of Paris St-Germain’s last-16 Champions League tie against his former club Barcelona with a thigh injury.
The Brazil forward was injured in PSG’s French Cup victory over Caen on Wednesday.
Mauricio Pochettino’s side travel to the Nou Camp on Tuesday (20:00 GMT).
PSG say they expect Neymar, 29, to recover in around four weeks, which could see him return for the second leg on 10 March.
Writing on his Instagram page on Thursday Neymar said: “The sadness is great, the pain is immense and the crying is constant.
“Once again, for a while, I will stop doing what I love most in life, which is playing football.
“Sometimes I feel uncomfortable because of my style of play, because I dribble and constantly get fouled, I don’t know if the problem is me or what I do on the pitch.”
Neymar helped PSG reach their first ever Champions League final in August and has scored 13 goals in 17 appearances this term.
It is a second blow for Pochettino, with winger Angel di Maria already ruled out of the match with a thigh injury.59
