Utah Jazz center Rudy Gobert will miss three to four weeks, a source confirmed to ESPN on Saturday, after he suffered a strained PCL in his left knee and a bone bruise during Friday's win over Boston.
Initial X-rays were negative, but Gobert, who is averaging 11.6 points, 9.6 rebounds and 2.3 blocks this season, had an MRI on his knee Saturday.
The Jazz said he'd be re-evaluated in two weeks. The Vertical first reported the time that Gobert is expected to miss.
He suffered the injury during Friday's 107-95 victory over the Boston Celtics, going to the floor awkwardly after appearing to get rolled into by teammate Derrick Favors early in the first quarter. As he tried to get back to his feet, Gobert fell back to the floor and rolled to his back before clutching his left knee.
Athletic trainers briefly attended to Gobert's left leg on the court before teammates picked him up and attempted to carry him to the bench. Gobert limped when he tried to walk under his own power.
Jazz coach Quin Snyder was glad the MRI results weren't worse.
"I was going to try the silver lining and I was going to say there really isn't one. That would be one," Snyder said before Saturday's game against the Cavaliers. "There's no question. You never know, and you have that moment where you just feel sick for the player. And particularly Rudy, knowing how hard he worked to come back when he did and to have that happen again.
"One thing about [him]: Rudy's resilient, and he's got a great approach. He's tough ... you look at him he's big and he's long, he's not 280, but he's tough. And it's a credit to him that he's able to bounce back the way he has. Again, the injury is such that hopefully he'll be able to do that quickly."
Gobert missed 11 games earlier this season with a bone bruise in his right knee.
