Professional golfers on the Ryder Cup team for both Europe and the United States want their event postponed, or cancelled because of the dangers of flying to England.
The NFL commissioner, Paul Tagliabue, is considering canceling Sunday's games for security reasons.
As of Wednesday, Major League Baseball had cancelled games through Thursday, with some officials predicting games would not start until Monday.
As I am writing this, ACC commissioner John Swofford, a former North Carolina Director of Athletics, is trying to reach the difficult decision on the status of this weekend's game.
I am glad I do not have to make Swofford's decision. Half-hearted debate has sprung up in the sports community about the wisdom of playing sports in the wake of the horrible tragedies visited upon New York City and Washington D.C., and, indeed, upon us all in America.
There are those who say games ought to continue so that the terrorists' attacks do not achieve their aim of destroying America's life. And on the other side, there are the people who cannot fathom something as trivial as sport playing in the face of this horror.
I can see both sides of the argument, but I think the most important question asked must be of the athletes' safety.
This weekend, teams from Georgia, New Hampshire, Pepperdine, Southern Methodist, West Virginia and Wisconsin are supposed to travel to Chapel Hill for contests against North Carolina's football, men's soccer and volleyball teams.
North Carolina's women's soccer team is supposed to travel to Houston for a tournament. The women are scheduled to play an exhibition game against the Mexican national team and then play Houston on Sunday.
