MOSCOW — Fourteen Russian athletes have now been banned for doping at the 2014 Sochi Olympics, with nine medals stripped from six athletes in four sports.

Here’s a look at the medalists who have been banned:


ALEXANDER ZUBKOV

Sport: Bobsled

2014 Olympic results: Gold in two-man, gold in four-man

Alexander Zubkov was arguably Russia’s biggest star at the Sochi Olympics, a grizzled veteran who carried the Russian flag at the opening ceremony and then won two gold medals in bobsled.

Zubkov has since become president of the Russian Bobsled Federation, putting him in charge of a new generation of athletes.

His gold medals are now in line to pass to Swiss and Latvian teams. American bobsledder Steven Holcomb, who died in May, could be upgraded to two silver medals.


OLGA FATKULINA

Sport: Speedskating

2014 Olympic result: Silver in 500 meters

Olga Fatkulina could only manage 20th in both her events at the 2010 Olympics, but the skater from the Ural Mountains improved rapidly over the following years to win a world title in 2013, then an Olympic silver medal the following year.

When the IOC announced she had been banned, Fatkulina was in Canada for a World Cup speedskating event.


ALEXANDER TRETYAKOV

Sport: Skeleton

2014 Olympic result: Gold

Alexander Tretyakov arrived in Sochi as Russia’s first skeleton world champion and broke the track record on his way to the gold medal.

Martins Dukurs, a five-time world champion from Latvia, is now in line to inherit his and his country’s first Winter Olympic gold.


ELENA NIKITINA

Sport: Skeleton

2014 Olympic result: Bronze

Elena Nikitina narrowly reached the podium, beating American rival Katie Uhlaender by 0.04 seconds for bronze.

Nikitina, one of three Russian women in the top six who have been found guilty of doping offenses, would have been a medal contender at the Pyeongchang Olympics. She won a World Cup race only four days before her ban was announced on Wednesday.


ALEXANDER LEGKOV

Sport: Cross-country skiing

2014 Olympic results: Gold in men’s 50 kilometers, silver in 4×10-kilometer relay

A Russian podium sweep in the last race of the Sochi Games meant Alexander Legkov got his gold at the closing ceremony. A packed stadium looked on as Russian cross-country skiers received gold, silver and bronze.

Legkov was a surprise winner because he had never won an individual or Olympic world championship medal in nine years of trying.

Legkov says he competed clean, and has never failed a test. Ilya Chernousov, Russia’s bronze medalist in the 50K, could now inherit gold.


MAXIM VYLEGZHANIN

Sport: Cross-country skiing

2014 Olympic results: Silver in men’s 50 kilometers, silver in 4×10-kilometer relay, silver in team sprint

Maxim Vylegzhanin never quite made it to the top of the podium, finishing second three times. He has now lost all three medals. Sweden, France and Norway are among the countries that could be upgraded as a result.
