Dustin Johnson headlines a list of late additions who will compete at TPC Four Seasons next week.
Johnson, the thirteenth-ranked player in the world and fifth in FedExCup points, has three top-20 finishes in four appearances at the HP Byron Nelson Championship.
Ryan Moore, who, lost to Adam Scott on the third sudden-death playoff hole in the 2008 Nelson, is playing in his fourth Nelson. Snedeker, the 25th ranked player in the world, a six-time PGA TOUR champion and 2012 FedExCup Champion, will make his third appearance at the Nelson.
The field will be finalized Friday.
