NAPLES, Fla. (AP) -- Defending champion Kenny Perry put off surgery on his left knee until next week so he could play in the Champions Tour's ACE Group Classic.
Hampered by torn cartilage, Perry had a cortisone shot about three weeks ago and is scheduled to have surgery Tuesday. He tied for 19th last week in the Allianz Championship.
Twenty-eight of the top 30 on the 2012 money list will open play Friday on TwinEagles' Talon Course, with 2009 champion Fred Couples and Corey Pavin skipping the event to play in the PGA Tour's Northern Trust Open.
Rocco Mediate is coming off a victory Sunday in the Allianz in his first start on the 50-and-over tour, while Scott Hoch, the 2008 champion, is returning from a thumb injury that sidelined him all of last year.
Heavy rain stopped play Thursday in the afternoon pro-am after most of the groups played nine holes. More rain is expected Friday.
