So, the Lakers lost 117-116 and are now 0-1 without James.
Lakers head coach Luke Walton said the decision on when James plays next will be made in conjunction with the superstar and the team's medical staff.
But the Lakers don't have anytime to lament what could have been.
James' recovery is being taken "day by day", according to the Lakers, with the team next in action against the Kings on Sunday. In those 10 games, he's averaged 9.8 points on 37.4 percent shooting from the field and 32.7 percent shooting from behind the arc.
Los Angeles Lakers snap an 11-game losing streak.
"I take a lot of pride in (staying healthy)", James said after the Warriors' game.
"Those type of things are what cost us the game, not not having him at the end or that shot that Bogdanovic hit", Walton said.
He suffered the injury when he reached awkwardly for a loose ball.
Point guard Rajon Rondo will also miss the game with the Kings due to a sprained finger. Los Angeles had seven turnovers in the first quarter but none in the second. No. 2 draft pick Marvin Bagley III remains sidelined with a left knee bone bruise. James is not expected to need surgery, but the groin strain could cause him to miss several games, including Friday against the Los Angeles Clippers.
