Los Angeles Lakers forward Larry Nance Jr. had an MRI exam Wednesday that showed a bone bruise, but was otherwise inconclusive because of swelling in his left knee.
The Lakers have said Nance will be out indefinitely. He will be re-examined by the team doctor Sunday.
Nance suffered the injury while chasing a loose ball during the third quarter of the Lakers' 117-113 loss to the Charlotte Hornets on Tuesday. Teammates helped Nance off the court.
Nance left the arena with the help of crutches.
Against the Hornets, Nance played for a little less than 21 minutes. He scored 10 points on four-for-five shooting with four rebounds, two assists, two steals and two turnovers.
Nance had a right knee contusion this month. He also suffered a torn knee ligament in college but that was also in his right knee.
This season, Nance is averaging seven points and 5.5 rebounds per game.
"Larry gives us a lot of versatility," coach Luke Walton said. "He's probably our most intelligent player as far as reading defenses and being able to cover for people. With him able to shoot, and roll to the rim, and get extra possessions for us, however long he's out is gonna be a huge loss for us."
