Kawhi Leonard is out for Game 4 of the LA Clippers' first-round series against the Dallas Mavericks.

Leonard, who has been dealing with inflammation in his surgically repaired right knee, had been listed as questionable for Sunday's game. The injury kept Leonard out for 22 days before he returned for Game 2, logging 35 minutes.

Clippers team president Lawrence Frank on Sunday called Leonard's inflammation "tricky" and said there's no timetable for when the star wing will be able to return.

Leonard gutted out 25 minutes and finished with nine points and nine rebounds in the Clippers' 101-90 loss in Game 3 on Friday night, which gave the Mavs a 2-1 series lead. Afterward, he revealed that the knee did not respond the way he had hoped after Game 2.

"When you watch him play, it was very obvious that is not Kawhi Leonard," Frank said Sunday.
