Leicester, Arsenal and Chelsea claim the publication of doping allegations made by the Sunday Times are "without foundation".
The three Premier League clubs were named in a Sunday Times report which claims a doctor - named by the newspaper as Dr Mark Bonar - had been secretly filmed allegedly discussing working with numerous professional athletes, who used banned treatments.
The report stated that Bonar had claimed to have treated players from Leicester, Arsenal and Chelsea.
However, those claims have been rejected by all three clubs, who also expressed their disappointment at the publication of the report.
And on Sunday evening Dr Bonar tweeted: "The @SundayTimesNews allegations are false and very misleading. I have never had a relationship with any premier football club or player."
Leicester said in statement: "Leicester City Football Club is extremely disappointed that The Sunday Times has published unsubstantiated allegations referring to players from clubs including Leicester City when, on its own admission, it has insufficient evidence to support the claims.
"Leicester City follows robust and comprehensive anti-doping protocols to ensure its full compliance and that of its players with all anti-doping rules and regulations."
A Chelsea statement read: "The claims The Sunday Times put to us are false and entirely without foundation.
"Chelsea Football Club has never used the services of Dr Bonar and has no knowledge or record of any of our players having been treated by him or using his services.
"We take the issue of performance-enhancing drugs in sport extremely seriously and comply fully with all anti-doping rules and regulations.
"Chelsea FC players are regularly and rigorously tested by the relevant authorities."
Arsenal, like Leicester and Chelsea, were similarly dismissive of the allegations.
"Arsenal Football Club is extremely disappointed by the publication of these false claims which are without foundation," a statement read.
"The club takes its responsibilities in this area very seriously and our players are well aware of what is expected. We strictly adhere to all guidelines set by the World Anti-Doping Agency."
