Gobert sprained his PCL and has a bone bruise on his tibia, according to The Vertical's Shams Charania.
The Jazz lost center Rudy Gobert early in the first quarter Friday against the Celtics, when teammate Derrick Favors landed on his left knee. Although, in the past, a typical Grad 1 MCL sprain requires a player to be sidelined for roughly two weeks.
While Gobert's knee buckled, he still tried to stand up, only to collapse to the floor.
He recently missed 11 games with a bone bruise in his right knee. If they can come close to that type of record during his absence, Utah should be fine. However, there's no limiting what this Jazz team can do. But the team just got more bad news. Therefore, this game is going to be potentially an even bigger challenge for the Jazz than the one they played last night.
The Utah Jazz will be without their defensive anchor for an extended period of time for the second time this season.
