​The Los Angeles Clippers are concerned that star Kawhi Leonard may have suffered an ACL injury, according to The Athletic's Shams Charania.

Leonard will miss Game 5 of the Western Conference semifinals against the Utah Jazz with a right knee sprain. He is out indefinitely, which means he could miss the remainder of the series.

Leonard injured his knee during Game 4 of the series on a late drive. He stayed in the game after tweaking his knee, but did not finish the Clippers' win over the Jazz.

The Clippers-Jazz conference semifinals series is tied at two games apiece. Game 5 is set for 10 p.m. ET Wednesday, Game 6 will be on Friday at 10 p.m. ET and Game 7 will be played on Sunday if needed.

If the Clippers advance to the Western Conference Finals next week, they may face a shorthanded Phoenix Suns team after Chris Paul reportedly was placed in COVID-19 protocols on Wednesday.

Leonard is averaging 27.3 points and 7.5 rebounds in the Clippers' four postseason games against the Jazz.
