The forward suffered a groin injury on Christmas Day against the Golden State Warriors.
James was forced out of the game, which the Lakers ended up winning 127-101.
According to ESPN, he is expected to miss ‘several games’ due to the problem, and even rival Steph Curry was full of support for the 34-year-old.
“You got to take those first four or five days, that was what my experience was, to make sure you don’t do any more damage,” Curry told The Undefeated.
”You have to let the healing process start. That is one you can’t really rush.”
But Walton explained that he has no real reason to worry yet.
The Lakers are also missing James’ fellow veteran Rajon Rondo due to injury, but the Lakers coach insisted that he is still confident in his young core of stars.
“I know we can get through it,” Walton said, per Lakers Nation.
“I know it’s not going to be easy, but I know and believe in the guys that we have.
“I thought at Sacramento [vs the Kings] we played a game on the road against a good team that we should’ve won.
“[On Friday] we had a 10-point lead late in the third.
“I know that’s not winning, but I believe the team we have can get it done.
“We just have to do a couple things a little bit better.”
The Lakers take on the Sacramento Kings on Sunday night in their final game of 2018.
Tip-off is at 2.30am UK time [10.30pm PT].
It is the second time the teams have squared off in just three days after the Kings beat the Lakers 117-116 on Thursday night.
