Bailly played his last game for Manchester United this season.
It confirms the club itself in a press release on Monday.
The cork fell after an hour on Sunday, after a grim confrontation with Chelsea's Matteo Kovacic.
Bailly has not figured under Solskjær since the deal against PSG at Old Trafford in early March, and now a new long awaits awaits the player's margin.
Now Manchester United reports that the cork suffered a knee ligament injury, so the fight against Chelsea was the last time we see the cork this season.
The damage is so serious that Bailly is not allowed to attend the African Summer Championship, which starts in Egypt on June 21.
For Manchester United, Huddersfield and Cardiff remain in the two remaining Premier League games.
There, Solskjær may have headaches with choices at the stopping place.
Phil Jones and Chris Smalling were not in the fight against Chelsea, which means that the only injury-free midfielder Solskjær currently has is Victor Lindelöf and Marcos Rojo.
