Among the NBA's short-term recommendations to teams in the wake of the coronavirus outbreak, players should utilize fist-bumps over high-fives with fans and avoid taking items such as pens, balls and jerseys to autograph, according to a memo to teams obtained by ESPN.

Among larger concerns being addressed in NBA front offices is the possibility that pre-draft combines, on-site workouts and international scouting events could become more limited in scope, or even be canceled, based on the possible escalation of the coronavirus outbreak.

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."

The league has also been constantly updating teams with the latest information available on dealing with coronavirus.

Some players are already taking the NBA's advice to heart.

"Corona," Bobby Portis of the New York Knicks said as he offered some fist-bump greetings on Monday night before his team faced the Houston Rockets.

Jimmy Butler of the Miami Heat said he wasn't necessarily worried or thinking about avoiding high-fives.

"I don't think about any of that," Butler said. "I'm still going to be who I am. We're still going to be who we are."

The Trail Blazers' CJ McCollum tweeted over the weekend about the need to take precautions and that he was taking a break from signing autographs for now.

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.



Sincerely,

But the Celtics' Kemba Walker said Monday that while he will be cautious, "I'm pretty sure I'm still going to sign some autographs, but maybe I'll just walk around with my own marker."

As the number of cases in North America starts to increase, there's been no impact in terms of curbing of league travel or games. An NBA player who contracted the coronavirus would expect to miss two weeks, one team medical official told ESPN. NBA front offices are preparing for scouting events such as the global Hoop Summit in Portland, Oregon, in April, and the NBA draft combine in Chicago in May, events that host of hundreds of players, coaches, front office personnel and medical staff.
