Manchester City defender Kolo Toure has been suspended from playing after testing positive for "a specified substance".

The club confirmed in a short statement on their website that Toure had been informed by the Football Association that an A-sample provided by him returned positive.

"He has been suspended from participating in all first team and non-first team matches pending the outcome of the legal process," the City statement read. "There will be no further comment from the football club at this stage."
