'The Bank of America Championship will not be played this weekend,' event spokesman Nick Ingala said.
Three storms dropped more than 5 inches of rain on the Nashawtuc Country Club course outside Boston in the past week to bring the area's total to more than 20 inches since the beginning of May. The Sudbury River overflowed its banks onto the first fairway, and four other holes were also flooded.
A regular Champions Tour event is scheduled for 54 holes; 36 holes must be completed for it to count as official.
The 2005 Bayer Advantage Classic in Kansas City was the tour's last event that was shortened, to 36 holes.
