Worcestershire County Cricket Club has been fined £600 by the England & Wales Cricket Board (ECB) Cricket Discipline Commission after played an unregistered player during the Friends Provident Trophy earlier this year.
Spinner Ian Fisher was the player who was not registered due to an administrative oversight by the county, who failed to register him despite the player always being eligible to be registered and play for the club.
Fisher was cleared of any blame, while Worcestershire apologised for its error, has accepted the fine and will be reviewing their future player registrations.
"In these circumstances the matter has been dealt with by way of summary procedure," an ECB statement read.
"However, the Commission wishes to underline the need for counties to ensure that players are properly registered and in timely fashion."
Worcestershire failed to progress from their Friends Provident Trophy group after they were beaten by Ireland in their final fixture at New Road.
