The Football Association (FA) has announced West Ham United have been hit with an anti-doping charge, with the Premier League club having a week to respond.
West Ham claim the breach is an administrative error on the part of the club and is not related to any of their players.
"It is alleged the club failed to ensure its 'Club Whereabouts' information was accurate on three occasions within 12 months," the FA said in a brief statement.
"West Ham have until 27 February 2018 to respond to the charge."
A spokesperson for West Ham indicated the club will be responding to the FA charge swiftly.
