Reports have claimed City signed the former Mancehster United striker this summer for around £47million.
The deal would have made Tevez the fifth most expensive player of all time.
Joorabchian told Sky Sports News in a statement: “Today’s story in The Times about Carlos Tevez is inaccurate and misleading.
“There appears to be the hand of mischief at work as the numbers quoted are fictitious.
“There was also no mystery about the true details as full disclosure was made to both the Football Association and Premier League.”
