Mike Weir, the 2003 Masters winner who was in Na’s group, said he recalled Na expressing some discomfort earlier in the round. 

"Right there on 10 tee," Weir said, via ESPN. "But he said earlier he wasn't feeling well. So I'm not sure what's happening, but he told me earlier he wasn't feeling well."

Na was one of 18 LIV Golf members competing in the 88-player field this week.
