Slovenia ice hockey player Ziga Jeglic has accepted an anti-doping rule violation and been suspended from the Winter Olympics.
Jeglic, 29, tested positive for asthma medication fenoterol in an in-competition test, the Court of Arbitration for Sport (Cas) said.
He is the second athlete to be banned from Pyeongchang 2018 and this is the third anti-doping case of the Games.
Forward Jeglic now has 24 hours to leave the Olympic Village.
Slovenia finished second in Group B of the men’s ice hockey preliminary round and face Norway for a place in the quarter-finals on Tuesday.
Jeglic, who plays in Russia’s Kontinental Hockey League, scored during Slovenia’s 3-2 group-stage win over Slovakia.
Fenoterol is an anti-asthma drug that opens up the airways to the lungs and is on the World Anti-Doping Agency (Wada) prohibited list.
Japanese speed skater Kei Saito was the first athlete to be suspended from the Games after testing positive for acetazolamide, a banned diuretic which is considered a masking agent.
Cas has also opened an anti-doping case against Russian medal-winning curler Alexander Krushelnitsky, who is suspected of testing positive for meldonium.

Jeglic has been a key part of the Slovenia team since 2009 and has scored a goal in every major tournament he has played in.
He was among their star players in Sochi four years ago and now he will leave his team-mates after accepting the ruling that he tested positive for fenoterol.
This news has come just before Slovenia’s game against Norway and will be a huge distraction as the rest of the team try to reach the quarter-finals without one of their best players.
