Toure has admitted his mistake and regrets the negative publicity which has deflected from Sunday's fundraising game for children's charity Unicef at Old Trafford.
"I would like to apologise to everyone involved in Soccer Aid for an inappropriate joke I deeply regret," he wrote on Twitter.
"It was meant as a joke however I lacked thorough consideration for the feelings of other participants.

"It's sad to see an inappropriate joke I made attract the attention which should be fully devoted to the beauty of the charity game.
