ITV has apologised to viewers after millions missed Everton's winning goal against Liverpool because the broadcaster cut to an ad break.
While some regions and digital viewers returned to the action just in time to see the only goal of the match, many were left in the dark over Dan Gosling's winner which sent Liverpool crashing out of the FA Cup.
Viewers returned to live coverage of the game in time to see goal celebrations, leaving many fans wondering what had just happened.
Match presenter Steve Ryder said: "If you missed the goal we apologise. It was because of technical problems we had at that time."
ITV said the problem occurred at the transmission centre and was not the responsibility of the ITV Sport production team, but the FA has demanded a full explaination.
ITV's executive chairman, Michael Grade, said: "Most importantly I'd like to apologise to all our viewers who were affected by last night's unprecedented technical error."
He added: "As a football fan myself I was glued to the match and was as disappointed as anyone to miss the goal.
"We have years of experience in dealing with the changes in ad break patterns when games go into extra time and sometimes penalties - this we have done faultlessly through the Champions League, World Cup and European Championships.
"Last night's glitch was inexcusable and we are awaiting the results of our technical inquiry so we can put in place stringent and immediate procedures to address this."
An FA spokesman said on www.thefa.com: "It is obviously very disappointing that viewers and fans did not see the only goal of last night's FA Cup replay between Everton and Liverpool.
"Clearly we are seeking a full explanation from ITV as to why this happened. It is important that lessons are learned and that this does not happen again."
