The Los Angeles Clippers will again be without superstar Kawhi Leonard for Game 2 of the Western Conference Finals due to a sprained right knee.

Leonard sat out the series-opening loss to the Phoenix Suns on Sunday, having suffered a knee injury in Game 4 of the Western Conference semi-finals.

Clippers forward Leonard will now miss his fourth consecutive game – Tuesday's NBA playoff clash with the Suns in Phoenix, head coach Tyronn Lue confirmed.

"He just stays engaged," Lue said on Monday. "He likes to know the adjustments we're going to make. He likes to know the game plan so when he watches the game, he can understand what we're doing good and doing bad, and let the coaches know, let the players know.

"He's very engaged. Even though he's back home rehabbing, he's still locked in and tuned in."

On keeping Leonard involved while sidelined, Lue added: "Just being able to hold guys accountable, talking to guys, talking to the players, what we need to do better on what he sees. If he knows the game plan, then he can definitely do that.

"So he's talked to the guys every day, as well, not just the coaching staff. He's very engaged and that's what you need from your players. He's locked in and still in tune."

In this season's playoffs, two-time NBA champion Leonard has been averaging 30.4 points, 7.7 rebounds and 4.4 assists for the fourth-seeded Clippers.
