After hearing a “pop” in his left knee on Tuesday, Kyrie Irving will have an MRI to determine the extent of the injury, according to the Akron Beacon Journal. Irving was able to return to the game—a 91-76 blowout loss to the Pacers—but said his knee still didn’t feel right:

Kyrie Irving will have an MRI on his left knee today after he was injured in the third quarter of Tuesday’s 91-76 loss at the Indiana Pacers. Irving said he felt a “pop” in his knee when he was driving to the rim, slipped and fell.

He stood up and walked gingerly toward the bench, then sat on the court, then rolled on his back as the Cavs medical staff attended to him. He was helped to the locker room without putting much weight on the knee, but still returned for the fourth quarter.

“Just a routine play. Just felt something pop in my knee a little bit,” Irving said. “I thought the worst had happened.”

Cavs coach Mike Brown and a handful of teammates met Irving as he lay on the court. He was cleared to return by the medical staff and played 9½ minutes in the fourth quarter following the injury. He missed the only shot he took, grabbed a rebound and had a steal and turnover.

“My left knee is pretty weak right now. I was falling all over the place,” Irving said. “I didn’t have my legs under me.”

Irving’s injury history is long and well documented. He missed 15 games his rookie season and 23 games last year with various illnesses and ailments. He said recently his goal for this season was to play in all 82 games.

“I’m still hoping that there’s nothing wrong, just something slight, if anything at all,” he said. “Just hoping for the best.”
