A full decision published by the International Olympic Committee (IOC) explaining their move to disqualify Alexander Zubkov from Sochi 2014 and strip him of the two gold medals he won there has listed "numerous elements" supposedly proving the Russian's involvement in doping.
Zubkov, who also carried the Russian flag at the Opening Ceremony of Sochi 2014 and is now President of the Russian Bobsleigh Federation (RBF), is among 25 athletes to have so far been retrospectively sanctioned.
He is the second to have their full decision published after gold and silver medal winning cross-country skier Alexander Legkov.
Like with Legkov, Zubkov submitted sample bottles bearing conclusive evidence of "multiple T Marks".
Extensive analysis carried out in conjunction with a Swiss Laboratory found that this proved they had been illegally re-opened and tampered with.
It is claimed there is no explanation for doing this other than to replace actual urine samples containing banned substances with clean supplies.
Zubkov also submitted samples showing salt levels which are "clearly non-physiological" which is viewed as an attempt to further mask doping.
He is included on the Duchess List of athletes drawn up by former Moscow Laboratory director turned whistleblower, Grigory Rodchenkov, who created a cocktail containing banned steroids and had test results switched to hide failures.
Rodchenkov also "specifically recalls" swapping sessions for Zubkov on February 5, 2014 and on February 23, 2014, with each time corresponding with entries in his diary.
