The Paris St-Germain striker Edinson Cavani is a doubtful injury to the first leg of the Champions League first knockout rounds on Tuesday at Manchester United, after injuring himself in a championship win over Bordeaux.
PSG's all-time best scorer kept his thigh after scoring a penalty and had to be replaced by Kylian Mbappe.
Cavani's attacker, Neymar, has already been excluded from United's games with a broken metatarsal.
"We have to wait, I do not have good news," said PSG manager Thomas Tuchel.
"Honestly, I do not know if Cavani will play, so it's worrying, we do not have another Edi as we do not have another Neymar".
PSG now have 13 points ahead of Ligue 1, but their victory over Bordeaux came after the hardest week of the season.
Sunday they lost for the first time in the league this season, 2-1 at Lyon, then they needed more time to beat Villefranche's third level in the French Cup on Wednesday.
