The Los Angeles Lakers could be without LeBron James against the Denver Nuggets on Sunday due to a thoracic muscle strain.
Lakers head coach Frank Vogel revealed the four-time NBA MVP did the damage during a 105-102 defeat to the Indiana Pacers on Wednesday.
James will be monitored, but the 34-year-old is a doubt for the showdown with the Nuggets at Staples Center, where the Lakers will attempt to stop the rot after back-to-back defeats.
"It was sustained in the Indiana game," Vogel said. "He played through it in the Milwaukee [Bucks] game, but the medical team is just keeping a close eye on him and list him as doubtful [to play on Sunday].
"If he doesn't go, it's going to be a group effort. We'll release starting line-ups tomorrow [Sunday], but it's one of those things that no one person can pick up what LeBron does for our team, so it will just have to be a group effort."
There is more positive news on forward Kyle Kuzma, who has been struggling with an ankle injury but is probable to face Denver.
The Lakers are 24-5 at the top of the Western Conference, while the Nuggets (19-8) occupy third place are have won their last five games.
