After leading the Lakers to a sizable lead, Lebron James left the game in the third quarter with what the team described as a strained left groin.
He did not return, but the Lakers had no trouble pulverizing the Warriors without him, rolling to a 127-101 victory at Oracle Arena.
There was obvious cause for concern for the Lakers not only because James is one of the greatest players of his generation but also because he is one of its most durable. Coach Luke Walton said James would undergo an magnetic resonance imaging exam on Wednesday to determine the extent of the injury; Walton did not offer a timetable for his return.
“Just overextended my groin, I guess,” said James, who did not rule out playing on Thursday against the Sacramento Kings. “It’s unfortunate.”
Now in his 16th season, James has never sustained a serious injury. Last season, he appeared in all 82 games for the Cleveland Cavaliers.
And the only season during which he missed more than 10 games was 2014-15, when he struggled with back issues. He rounded into shape in time to lead the Cavaliers to the N.B.A. finals.
After Tuesday’s game, James said he “takes a lot of pride” in not missing games because of injuries.
