Ernie Els is swapping out Tiger Woods' Northwestern Mutual World Challenge for the Nedbank Golf Challenge in his native South Africa.
Els made the switch citing a "family" decision. It'll mark the 17th consecutive year Els has played in the 30-player event in Sun City, a tournament he's won three times.
Dustin Johnson will replace Els in Woods' annual 18-player December event at Sherwood C.C. in California. Players are invited to the Woods event based on the Official World Golf Ranking. After winning the WGC-HSBC Champions, Johnson is now ranked 12th in the world.
The Northwestern Mutual World Challenge and Nedbank Golf Challenge will be played Dec. 5-8.
