Can someone give me a list of all the players who are going to participate in the Deutsche Bank tournament in Massachusetts?

Here is the FedEx cup points standings of the 144 players who are eligible to play. Does not mean they will all show up.

Sure. The field is linked below.

Those that qualified but will not play include:

· Tiger Woods (knee surgery, out until 2009)
· Luke Donald (wrist surgery, out until 2009)
· Lee Westwood (playing in Scotland this week)
· Justin Rose (playing in Scotland this week)
· Alex Cejka (after spending a week in the Czech Republic sponsoring a Challenge Tour event, he will take another week off to rest a sore arm)

This leaves 115 of an eligible 120 in the field. Monitor the link as it will get updated to acknowledge any withdrawals. There r no alternates in the playoffs.
