Julius Randle and Nick Young are doubtful for Lakers game against Warriors on Friday

The Lakers could be down three starters when they host the Warriors at Staples Center on Friday night.

At shootaround Friday morning, Lakers Coach Luke Walton said both Julius Randle (hip pointer) and Nick Young (sprained toe) are doubtful for the 7:30 p.m. tip off.

Randle did not play in the Lakers’ 149-106 loss to the Warriors in Oakland on Wednesday. He was replaced by rookie Brandon Ingram in the starting lineup, and Ingram scored a career-high 16 points in 34 minutes. Randle tried to run during shootaround but stopped when his injury tightened up, Walton said.

Young played against the Warriors on Wednesday but was in treatment for the length of Friday’s shootaround, according to Walton. Young said after Wednesday’s loss that he thought his toe may be broken. The Lakers said that was not the case, but Young was playing through pain nonetheless.

The Lakers (8-8) are already playing without starting point guard D’Angelo Russell, who is expected to miss at least another week and a half with a left knee injury. Walton has not yet decided how he would compensate for three missing starters against the Warriors (13-2), whom the Lakers upended at Staples Center on Nov. 4 before losing by 43 on Wednesday.

Young is averaging 13.9 points per game this season. Randle is averaging 13.3. Russell is the team’s second-leading scorer at 16.1 points per game. Without all three in the lineup, the Lakers would have only two healthy players — Lou Williams and Jordan Clarkson — averaging 10 or more points a contest.

“A set contingency on if three of your starters are hurt?” Walton said, smirking, at the Lakers’ practice facility Friday morning. “No, we’ll have one before game time.”

Walton has tried to keep his bench lineup of Williams, Clarkson, Ingram, Larry Nance Jr. and Tarik Black together so far this season, but said that probably would not be an option if Young and Randle can’t go.

The Lakers are the only team to hold the Warriors below 100 points this season. But the Warriors’ ability to pick on the young Lakers was made apparent on Wednesday, as the Warriors assisted on 47 of their 53 field goals.

Walton called the Warriors’ offensive display “beautiful” and their assists total “one of the greatest stats I’ve ever heard or seen.” He knows his team is in for another tough test on Friday, and does not think they need a handful of injuries in order to make the game a teaching point in their growing process.

“Everything’s a good test for us, we don’t need injuries thrown on top of it,” Walton said. “The schedule we’re going through right now, whether we’re 100% healthy or not, is a tough schedule. But yeah, it’s definitely going to test our grit out.”
