Thomas Tuchel, who hopes to let go of his crutches by the end of the week, did not hide his concern after the injury-free exit of Juan Bernat (27), Wednesday at the Parc des Princes against Metz (1-0).
The first examinations, carried out in the field and then in the locker room by Christophe Baudot, the club's doctor, left him afraid of "a major injury".
The verdict fell this Thursday morning, confirming the serious diagnosis.
"The examinations performed this morning confirm the isolated rupture of the anterior cruciate ligament of the left knee", indicates the press release on club.
This serious injury usually keeps top footballers away from competition for almost 6 months.
The "isolated" rupture indicates that the injury is not associated with other complications (especially the meniscus).
Bernat, who entered the game in the 63rd minute, had to leave the pitch in the 86th minute, seeming to suffer martyrdom.
No return before March?
This injury comes less than a year from the end of the Spaniard's contract, a centerpiece of PSG since his arrival from Bayern Munich.
Negotiations for its extension had so far not been successful.
He should not find the land before March, if we refer to the classic deadlines.
This injury is added, at the left side position, to the suspension of Layvin Kurzawa for six games (including that of yesterday), following his expulsion at the end of the game against OM (0-1) .
The defender who extended his four-year contract this summer will be missed by PSG in the league until the November 1 match in Nantes.
He will nevertheless be able to participate in the first two days of the Champions League at the end of October.
For the other meetings, Paris will have to deal with the young Mitchel Bakker, 20 years old and 3 Ligue 1 games on the clock, or Abdou Diallo, when he has served against Nice on Sunday his suspension following his expulsion against Metz.
Unless PSG decides to recruit for this position, which was probably not on the roadmap of Leonardo whose budget is restricted this summer.
