It is alleged that Chelsea FC has breached Regulation 1(e) of The FA's Doping Control Regulations, which states that interference with a drugs test or the Doping Control Programme will be regarded as amounting to a breach of the Doping Control Regulations.

Paragraph 12 of the Definitions and Descriptions of Doping Offences states that:

"The independent private testing/screening of players by clubs, club officials or any other person subject to Football Association Rules is prohibited. Such testing/screening will be regarded as conduct that would interfere with The Football Association's Doping Control Programme contrary to paragraph 1(e) above and penalties may be imposed accordingly...".

The club has until 23 September to respond.

Note: FA Rule E25 states that:

"A participant shall comply with the provisions of any doping control regulations as shall be in force from time to time as determined by the Council."
