Ireland's Paul McGinley fears retaliation by America over the terrorist attacks this week will place the Ryder Cup in even greater jeopardy.
Serious doubts have already been raised about the contest being staged at The Belfry on September 28-30 with several players expressing their concern about travelling and whether it is appropriate to play after such a tragedy.
The majority of this week's sporting events in America - and others around the world - have been postponed or cancelled as a mark of respect, including the 5million US dollars World Golf Championships event in St Louis.
McGinley said: "The Ryder Cup decision must be made democratically and I think we are going to have some Americans not wanting to come.
"The problem will be that you are going to have some kind of retaliation from the American government in the next two weeks. That will be the bigg est problem. "It's a horrible situation and a horrible decision to have to make." However, there appears to have been a change in opinion among the American players, particularly Mark Calcavecchia who earlier this week had called for the cup's postponed.
"You've got to move on. If you don't, you're giving in," he said. "Time heals all wounds, and maybe next week it won't seem so bad."
