UEFA have launched an investigation after Manchester City midfielder Toure claimed CSKA fans subjected him to monkey chants during Wednesday's UEFA Champions League clash at Arena Khimki.
Doumbia was subsequently quoted as saying his fellow Ivorian had overreacted when he spoke out after the game.
A statement on Doumbia's Facebook fanpage read: "I want to clarify my position after my Ivory Coast team mate and friend Yaya Toure accused CSKA fans of racism.
"I want to insist that I did not talk to any journalist about these facts so none of the quotes you read in the press came from me."
The governing body have a three-step protocol that states that referees should halt the game if they become aware of racial abuse and an announcement should then by made over the public address system warning fans to "desist from such racist behaviour".
