The Utah Jazz fear that forward Joe Ingles suffered a significant left knee injury during Sunday’s 126-106 loss to the Minnesota Timberwolves, and the team will await results of an MRI set for Monday to learn the full extent of the injury, sources told ESPN.

Ingles’ knee buckled on a drive to the basket, causing him to crumple to the court in the second quarter. Ingles needed help to get to the locker room, and sources tell ESPN that an initial examination fueled considerable concern of a serious knee injury.

Ingles has been a vital part of the Jazz for eight seasons, averaging 7.4 points, 2.9 rebounds and 3.5 assists this season in 25.2 minutes per game. He was the runner-up to teammate Jordan Clarkson for the NBA Sixth Man of the Year Award last season.

Ingles is in the final year of a contract that pays $13 million in 2021-22.

All-Star guard Donovan Mitchell missed his seventh straight game with a concussion on Sunday, and All-Star center Rudy Gobert missed his fourth game with a left calf strain.

The Jazz had dropped four straight and eight of 10 games to move into fourth place in the Western Conference prior to Sunday night’s loss.
