Thomas Pieters withdrew from the European Tour's KLM Open in the Netherlands on Thursday after a bad reaction to a bee sting.
The 24-year-old Belgian didn't show up for his Thursday tee time at The Dutch, with organizers saying Pieters had an allergic reaction.
"One bee sting on Monday during the golf challenge against Joost Luiten led to a major allergic reaction with flu symptoms, and forced me to pull out of my favorite tournament of the year," Pieters said in a statement posted on his website and social media accounts.
The Ryder Cup rookie went on a recent tear to earn one of three captain's picks from European skipper Darren Clarke. He finished fourth in the men's Olympic tournament, second in the D+D Real Czech Masters and won the Made in Denmark tournament in his last three starts.
