LOS ANGELES (AFP) - Basketball superstar LeBron James said on Friday (March 6) that he will not play if his Los Angeles Lakers have to hold NBA games behind closed doors due to the coronavirus outbreak.

The National Basketball Association has reportedly told teams to look into strategies on how to play without fans in the arena amid concerns over the spreading virus.

"Nah. It's impossible," James said after the Lakers' 113-103 win over the Milwaukee Bucks.

"If I show up to the arena and there ain't no fans in the crowd, then I ain't playing."

The league sent a memo to each team on Friday asking them to develop contingency plans to combat the spread of the virus. One of the alternatives is playing games behind closed doors.

"I ain't never played the game without no fans," James said. "Ever since I started. This ain't Europe.

"I play for my teammates and I play for the fans. That's what it is all about."

James and Anthony Davis scored all but one of the Lakers' points in the final quarter on Friday as they rallied to beat the NBA-leading Bucks and clinch their first play-off spot since 2013.

No high-fives

As fears grow over the spread of the virus, and sports leagues formulate contingency plans, the NBA's memo told teams to start "developing" plans on how to play games with only "essential staff" in attendance, American sports broadcaster ESPN reported.

The NBA had sent out a previous memo to teams earlier this week, recommending players to use fist-bumps instead of high-fives with fans. It also said to avoid taking items such as pens, balls and jerseys from fans to sign.

"The health and safety of our employees, teams, players and fans is paramount," the organisation said in a statement on Monday.
