The WGC - American Express Championship will not begin play until Friday when the field is scheduled to play 36 holes. Saturday and Sunday will be played as usual with 18 holes each day.
The Tampa Bay Classic will not play its scheduled Wednesday Pro-Am and will also not begin round one until Friday. Due to the larger field, 18 holes will be played Friday and Saturday at which point a cut will be made. Those making the cut will play 36 holes on Sunday to determine the winner.
The Buy.Com Tour's Oregon Classic will also play 18 holes Friday and Saturday then 36 holes on Sunday.
The Senior PGA Tour's Vantage Championship will remain a three-day event beginning, as scheduled, on Friday. However, both Wednesday and Thursday's pro-am rounds have been cancelled.
The precautions are in reaction to terrorist attacks that began in New York Tuesday morning when two planes crashed into both World Trade Center buildings, resulting in the eventual collapse of both buildings. Later Tuesday morning, another aircraft crashed into the Pentagon in Washington, D.C.
'Everyone at the PGA Tour shares the grief felt around the country at the tragic developments that have taken place today,' Finchem continued. 'Our thoughts and prayers are with the victims of these tragedies and their families and friends.'
The LPGA's Safeway Classic in Portland, Ore. is so far unnafected due to its Friday start. 'Once we have more information, we will determine whether any adjustments to our schedule are appropriate,' LPGA commissioner Ty Votaw said in a statement.

The USGA also announced it will confer with the eight contestants that have reached the quarterfinals at both the U.S. Senior Amateur and U.S. Senior Women's Amateur to determine their views on whether to maintain the planned schedule of the competitions or to reschedule. The events are taking place in St. Louis and Pittsburgh, respectively.
And, regarding the possible effects on this month's Ryder Cup, PGA of America CEO Jim Awtrey said 'Right now our concern is focused on those who are directly affected by today's devastation. I don't think it is appropriate for us to comment on anything else at this time.'
