Clippers All-Star Paul George left Tuesday night’s 101–100 loss to the Thunder late in the fourth quarter after appearing to suffer a rather a frightening leg injury. 

With just under five minutes remaining in the Western Conference tilt, George leapt up for a rebound alongside Thunder guard Luguentz Dort. While in the air, George’s right knee appeared to collide with Dort’s right leg, causing the Clippers star to land awkwardly and immediately fall to the floor. 

George remained on the ground in obvious pain for a few minutes before he was helped back to the locker room with 4:38 remaining in the game. He racked up 18 points, seven rebounds and five assists prior to leaving the contest. 

According to ESPN’s Ohm Youngmisuk, George left Arena on a cart with his right leg extended. The Clippers did not offer up any official update on George after the game, but coach Ty Lue said that the 32-year-old was undergoing further evaluation. 

A serious injury to George, who was selected to his eighth All-Star team this season, would be devastating news for the Clippers. George has been a steadying presence for Los Angeles throughout the year, having played in 56 games thus far and averaging a team-high 23.8 points, along with 6.1 rebounds and 5.1 assists.

The Clippers (38–35) had won five of their last six games prior to Tuesday’s loss, vaulting them into fifth in the Western Conference with nine games remaining.
