Damian Lillard left Game 4 of the Portland Trail Blazers' playoff series with the Los Angeles Lakers because of a right knee injury.
Lillard, who was the MVP of the seeding games in the NBA bubble in Florida, had 11 points before leaving the game in the third quarter Monday night. He left the floor for a time after his knee appeared to buckle, then returned briefly before leaving again.
No further details about the injury were immediately available.
Lillard, a five-time All-Star for the Trail Blazers, averaged 30 points and eight rebounds in the regular season.
