According to a memo obtained by ESPN, league officials are telling players they should avoid high-fiving fans. Instead they are being told to use the fist-bump.
Players are also told to avoid using a fan's pen for autographs and don't take a ball or jersey from the crowd to sign.
The Portland Trail Blazers' CJ McCollum took it a step further, saying he won't be signing anything for the time being.
The Corona Virus has officially hit Oregon. More specifically Lake Oswego...Make sure y’all washing y’all hands with soap for 20 or more seconds & covering ya mouths when you cough. I am officially taking a break from signing autographs until further notice.— CJ McCollum (@CJMcCollum) February 29, 2020
The NBA and National Basketball Players Association have been consulting with the Centers for Disease Control and Prevention and infectious-disease experts, including a renowned researcher at Columbia University, the memo said.
"The coronavirus remains a situation with the potential to change rapidly," the league told teams in the memo.
The NBA issued a statement to the AP, saying, "The health and safety of our employees, teams, players and fans is paramount. We are coordinating with our teams and consulting with the CDC and infectious disease specialists on the coronavirus and continue to monitor the situation closely."
An NBA player who contracted the coronavirus would expect to miss two weeks, one team medical official told ESPN.
