The Tuesday winner will face the New Orleans Pelicans in a Thursday semifinal at Las Vegas. The Pelicans earned a 127-117 road win over the Sacramento Kings in a Monday quarterfinal matchup.
James showed he is as feisty as ever during Los Angeles’ 107-97 victory over the Houston Rockets on Saturday. He backed into the lane for a 360-degree reverse layup and also earned a technical foul for a verbal spat with Rockets coach Ime Udoka in the fourth quarter. Udoka was ejected from the game.
James (left calf contusion) was listed as questionable for the Phoenix game as of Monday.
The Lakers opened their in-season tournament group-stage schedule with a 122-119 victory at Phoenix on Nov. 10. Los Angeles had to overcome a seven-point, fourth-quarter deficit in order to end a three-game losing streak.
Starting with that game, the Lakers are on a 9-4 run.
The Suns have won eight of their 10 games since losing to the Lakers, including a seven-game winning streak that helped them to a 3-1 record in West Group A play.
Phoenix enters the tournament quarterfinals off a 116-109 home victory over the Memphis Grizzlies on Saturday, when Devin Booker tallied 34 points, 10 rebounds and seven assists.
In nine games since returning from an early-season calf injury, Booker has averaged 27.1 points and 7.9 assists. He sat out Friday against the visiting Denver Nuggets in the opener of a back-to-back set, and the Suns lost 119-111.
The Suns still are waiting to see stars Kevin Durant, Bradley Beal and Booker on the court at the same time. Beal has played in just three games as he deals with a back injury, and he will remain sidelined on Tuesday.
Durant and Booker are at least getting a chance to nail down their on-court chemistry.
Durant is averaging 31 points with 6.4 rebounds and 5.8 assists through 18 games this season, while Booker is at 27.9 points, 5.8 rebounds and 8.4 assists through 11 games.
Phoenix’s Eric Gordon (right knee contusion) is questionable for the Tuesday contest.
