Cork played Monaghan in their Ladies Football Senior Championship qualifier at O'Connor Park in Tullamore on Monday afternoon.
Cork won by a single point to set up a quarter-final with Galway.
With just 10 minutes to the hooter, it was Monaghan who grasped the advantage in the game when Ciara McAnespie raised the green flag.
The decision to allow the goal came via the first ever use of the video review system in ladies football. McAnespie's shot had hit the crossbar and bounced down. Whether or not it had crossed the line evaded the attention of the umpires.
GOOAAALLL!! @MonaghanLadies are back in front thanks to a Ciara McAnespie rasper!! Score Assistant's first ever use thanks to @TG4TV

The decision took less than a minute to make and saw Monaghan go from two points down to a point ahead.
Cork would retake control of the game with Eimear Scally a vital player.
Earlier this year, the LGFA announced its decision to introduce a 'Scores Assistant' with the help of TG4. The assistant official sits in the TG4 production unit and can use all available angles to decide if a score has taken place.
