Manchester City defender Kolo Toure was suspended after failing a drugs test on this day in 2011.
Toure, who tested positive for a “specified substance”, was later banned for six months.
He blamed the failed test on taking water tablets belonging to his wife.
The Ivorian defender was informed by the Football Association that his A sample returned a positive result and that he was now unavailable to take part in any matches until the issue had been investigated.
The WADA punishment for such a positive test ranged from a warning to a two-year ban.
Hamilton midfielder Simon Mensing had recently served a four-week ban after he tested positive for a specified substance.
Toure’s failed test automatically triggered the suspension, with City left with no option but to exclude him from their plans until the conclusion of proceedings.
“There will be no further comment from the football club at this stage.”
Toure made his return from the ban in City’s 2-0 League Cup win over Birmingham in September 2011.
He went on to play for Liverpool and Celtic and is currently first-team coach at Leicester.
