DALLAS (AP) — Los Angeles Clippers forward Kawhi Leonard has been ruled out of Sunday’s Game 4 of a first-round series against the Dallas Mavericks, with no timetable for his return from right knee inflammation.

Leonard played in the second and third games of the series after missing the final eight games of the regular season and the series opener.

The six-time All-Star never looked comfortable in the Clippers’ 101-90 loss in Game 3, finishing with nine points on just seven shots, his fewest in a playoff game in 10 years. Leonard played 25 minutes as Dallas took a 2-1 series lead.

“When you watch him play, it was very obvious that is not Kawhi Leonard,” team president Lawrence Frank said before the game, calling the injury “tricky.”

He added the Clippers don’t know when the 32-year-old’s surgically repaired knee might be ready for a game.
