Tyronn Lue is confident the Los Angeles Clippers can turn around their 3-1 deficit in the Western Conference Finals with the Phoenix Suns, describing the challenge as "very doable".

The Clippers fell to an 84-80 loss to the Suns on Saturday, leaving Los Angeles needing to win three straight games to progress to the NBA Finals for the first time in franchise history.

In Conference Finals, teams that have led 3-1 have gone on to win a seven-game series 52 times, with that advantage reversed on just four occasions.

Falling 3-1 behind is typically a death knell for a team in any round, with teams that have claimed 3-1 leads in best-of-seven series winning 95 per cent of the time (251-13).

But Lue has experience of coming from 3-1 down to prevail, having done so as head coach of the Cleveland Cavaliers when they incredibly overturned that deficit to beat the Golden State Warriors in the 2016 NBA Finals.

The Warriors did not surrender the same lead in 2017, avenging that loss with a 4-1 Finals win over the Cavs.

Drawing inspiration from the Clippers coming from 2-0 down against the Utah Jazz in the previous round, Lue stated his belief in his team to overcome the odds.

"We beat Utah and won four games in a row," Lue said. "So it's very doable."

The Clippers' hopes of fighting back would be significantly boosted were Kawhi Leonard to return from a knee sprain that has seen him miss the final two games of the Jazz series and all four games with Phoenix so far.

But Paul George, who had a double-double with 23 rebounds and 16 rebounds in Game 3, does not want Leonard to rush back regardless of the Clippers' perilous situation.

"I can't speak for him, to the health of Kawhi," George said. "If he's not 100 [per cent], we don't want him out there. I mean, that's just as a brother, as a team-mate.

"His health long term is more important than what's going on now. I can't speak on the extent of his injury or, you know, what he [can] and cannot give us.

"Like I've been saying, his health is just more important than anything else."
