FILE - In this Aug. 11, 2011, file photo, Lucas Glover hits a drive on the 10th hole during the first round of the PGA Championship golf tournament at the Atlanta Athletic Club in Johns Creek, Ga. Glover sprained his right knee in a freak paddle board accident and might not be able to start his season at the Tournament of Champions, Glover said Thursday, Jan. 5, 2012.

KAPALUA, Hawaii — Former U.S. Open champion Lucas Glover has withdrawn from the season-opening Tournament of Champions after spraining his right knee while paddleboarding.

It's the second straight year a player has had to withdraw after getting injured in the ocean. Geoff Ogilvy cut open a finger on a piece of coral last year.

Glover was paddleboarding Saturday in the Pacific when his foot caught the side of the board and led to sprained ligaments.

Without Glover, that leaves 27 players in the winners-only field to start the season. It's the smallest field since the event moved to Kapalua in 1999.
