LONDON (AP) Two months after the closing ceremony, the Sochi Olympics broke a Winter Games record Friday when a Latvian hockey player became the eighth athlete disqualified for a positive doping test.
Ralfs Freibergs was retroactively kicked out of the games by the IOC after being found guilty of a steroid offense, the third hockey player and second from Latvia caught for doping in Sochi.
The International Olympic Committee said the 22-year-old defenseman tested positive for a testosterone-related steroid in a sample provided after Latvia's 2-1 loss to Canada in the quarterfinals on Feb. 19.
Ice hockey at the Olympics has changed plenty since it made its debut outdoors at the Winter Games in 1924. Rules have been modified, the format has changed and amendments have been introduced to allow professionals to compete. While the basics of the game remain constant in North America and throughout the rest of the world, many differences will be noticed at the 2014 Olympics in Sochi. The best players in the world will compete under international rules. Take a look at the game's history along with how the game differs between North American and international competition, from rink dimensions to fighting tolerance.
