Cavani picked up the injury at the end of the first half and he limped off the pitch holding his right thigh shortly after scoring the only goal with a penalty.
"It's super hard. If we miss several players the challenge will be even bigger".
"In any case, we must wait a bit more as the exams are still ongoing".
Speaking after the game, PSG coach Tuchel said: "Not good news". The sight of the injury worries me.
Paris Saint-Germain manager Thomas Tuchel faces the task of drumming up an emergency plan for the visit to Manchester United in the last 16 of the Champions League in the definite absence of Neymar and the possible unavailability of Uruguay forward Edinson Cavani.
It was first confirmed a couple of weeks ago that Neymar would miss the Man United vs PSG encounter due to a foot injury and the Brazilian will also not be available for the return leg. Since then, the Red Devils are yet to lose a game and they have dropped just 2 points across all competitions thereby proving that Manchester United still have it in them to compete on the biggest stage.More news: Cheers, jeers on border as Trump pushes wall in State of Union
'We don't have good news for Edi.
"I am anxious, but only because we are missing key players".
"There are a lot of plans B. Without Ney, maybe without Marco, maybe without Edi".
Manchester United star Alexis Sanchez has backed his team to go past PSG in the upcoming Champions League clash.
PSG is already without Neymar for the next two months, and although midfielder Marco Verratti started against Bordeaux he is way short on match sharpness. Verratti played nearly an hour before being substituted by Leandro Paredes.
