The Knicks are postponing the 50th anniversary celebration of the 1969-70 championship team on March 21 because of the coronavirus, according to sources.

Team officials have started to reach out to the Knicks legends of their first title team to inform them of the cancellation, and have not ruled out rescheduling.

According to sources, some players expressed concern to the organization about flying amid the crisis. According to the CDC, elderly are considered most vulnerable to the virus and flying is also deemed a risk of attracting germs.

All of the players on the 1969-70 are over 70 years old. The Knicks planned to honor the living members of the team during a halftime ceremony of their game against the Warriors.

Luminaries such as Walt Frazier, Willis Reed, Bill Bradley and Dick Barnett were planning to attend. Reserves John Warren, Don May and Cazzie Russell were also in.

According to a source, Phil Jackson, who was on injured reserve that season, had turned down the invite. Broadcaster Marv Albert wasn’t invited at all. But now the legends are being told it’s off. The Knicks announced the March 21 celebration 11 days ago.

The NBA, in memos, prepared teams to carry on with their schedule possibly without fans in attendance in the future.
