Hearts have admitted that they fielded an ineligible player in error during their League Cup win over Cove Rangers and have apologised, revealing that they will attend an SPFL disciplinary hearing where they may face punishment.

The Edinburgh side were 2-1 winners at Balmmor Stadium but brought on substitute Andrew Irving in the second half. Irving was not properly registered with the Scottish FA and his involvement breaches SPFL competition rules.

Hearts chair Ann Budge apologised to all concerned, saying that the breach was "inadvertent". Budge explained that processes were in place to avoid such errors but said that "mistakes can happen".

The club will now put in additional checks to prevent any repeat.

An SPFL disciplinary hearing has been scheduled for July 23, where Hearts will be represented. SPFL rules have no set sanction for the specific rule breach but action can range from a warning to the result being annulled or the match being replayed. The rules also carry more sever sanctions that are unlikely to be used in this case.

In a statement on the hearts website, Budge said: "It is with much embarrassment that we have to advise that during last night's Betfred Cup group stage match away to Cove Rangers, Hearts inadvertently fielded an ineligible player.

"Due to an administrative error on the club's part at the end of the January transfer window, Andrew Irving entered the field of play in the 65th minute as an unregistered player. Andrew was given an extension contract in January, 2018 and his extension paperwork was all properly completed and in order. However, it was not loaded onto the online SFA registration system at the time. His official registration, therefore, ran out on 9th June, 2018. Unfortunately, this was not picked up in advance of last night's game.

"While stringent processes are already in place to try to prevent something of this nature occurring, clearly mistakes can happen. An additional step in our internal procedures will be implemented immediately to try to ensure this cannot happen again.

"The club would like to apologise to its supporters, to Cove Rangers Football Club and to the footballing authorities for this inadvertent breach of the rules.

"A hearing with an SPFL panel has been scheduled for Monday, July 23rd and will be attended by representatives of the club, where sanctions against Hearts will be determined. Until then, no further comment will be made."
