The PGA Tour has suspended South Korean player Byeong Hun An for three months for violating the tour’s anti-doping policy.
The suspension has been retroactively applied to begin on August 31 and he will be eligible to return to competition on December 1.
PGA Tour officials said that An tested positive for a prohibited substance contained in an over-the-counter cough medicine that the 32-year-old player had bought in South Korea.
“He has co-operated fully with the Tour throughout the process and accepted his suspension,” read a statement from the PGA Tour. “The Tour will have no further comment on the suspension at this time.”
An, who is currently 53rd in the world rankings, won the BMW PGA Championship in 2015 and has four runner-up finishes on the PGA Tour, most recently at this year’s Wyndham Championship, which was held in August.
