Ennis-Hill originally won World Championships silver in 2011, but the Court of Arbitration for Sport has disqualified Chernova

Jessica Ennis-Hill is set to become a three-time world heptathlon champion after the Court of Arbitration for Sport (CAS) ruled that Russia’s Tatyana Chernova would be stripped of the 2011 World Championships gold having committed blood doping offences.

Chernova beat Britain’s Ennis-Hill in Daegu five years ago, but was banned from the sport in 2013 after a reanalysed urine sample from 2009 returned positive.

The Russian subsequently had a ban backdated, though the suspension handed to her by the Russian Anti-Doping Agency (RUSADA) ended just 16 days before the World Championships, meaning she was initially allowed to keep her gold.

However, CAS has ruled that Chernova will be banned for three years and eight months starting from February 5, 2016, for a separate offence and have all results, prize money and titles stripped from her from between August 15, 2011, and July 22, 2013.

A CAS statement read in part: “Tatyana Chernova is sanctioned with a period of ineligibility of three years and eight months, beginning on 5 February 2016. Ms Chernova’s period of suspension from 22 July 2013 until 21 July 2015, previously imposed by the Russian Anti-doping Agency (RUSADA), is to be deducted from this sanction. All results achieved by Tatyana Chernova between 15 August 2011 and 22 July 2013 are annulled and the athlete will forfeit any titles, awards, medals, points and prize and appearance money obtained during this period.”

Therefore, Chernova also loses her Olympic bronze medal claimed at London 2012.

Adding the 2011 title to her haul would make Ennis-Hill only the second heptathlete in history to win three world titles, with Sweden’s Carolina Kluft.

Ennis-Hill, who announced her retirement in October, wrote on Instagram: “So happy to finally be receiving my gold medal. Triple World Champion WOW.”

CAS also confirmed that middle-distance runners Kristina Ugarova and Ekaterina Sharmina had been handed backdated two and three-year suspensions, respectively, for anti-doping violations.

Due to the suspension of the All-Russia Athletics Federation (ARAF), CAS acted as a first instance decision-making authority in each of the matters.
