Manchester City have been fined £35,000 after admitting a breach of the Football Association's anti‑doping rules.
Clubs are required to provide accurate details of training sessions and player whereabouts so they are available for testing at all times.
City failed to ensure their information was accurate on three occasions.
It is understood the information was not updated following a change to training routines.
The punishment was imposed following an independent regulatory commission hearing, with the club also warned about future conduct.
Meanwhile, the match between Manchester City and Manchester united has been postponed due to United’s involvement in the EFL Cup final against Southampton.
The next match will be played on 26th of this month between Crystal Palace and Middlesbrough at 3am.
