AC Milan have included Olivier Giroud in the goalkeepers list on their website after yesterday night’s save.
The Milanese club's No 1 Mike Maignan picked up a late red card during the San Siro clash for a foul on Caleb Ekuban in stoppage time, after the club had used up all of its substitutions.
Stefano Pioli then tapped the World Cup winner to pull on the gloves, donning Maignan's distinctive green shirt.
The visitors threatened against 10-man Milan, with Albert Gudmundsson's freekick nicking the bar, but it was Giroud's quick-thinking that saw the former Chelsea star block Genoa's final run at an equaliser.
Giroud dived at a chancing ball from George Puscas, before leaping on top of it to snuff out the scoring opportunity.
Milan were quick to capitalise on his surprise star turn, listing the player under the 'goalkeepers' section in the squad on their website, and allowing fans to buy goalkeeping kit with his name and number.
But shortly after the decision was shared on social media, supporters flocked to snap up the shirts, and they have quickly sold out.
Giroud's efforts saw Milan hold onto their febrile lead, and took them top of the Serie A table at the end of the matchweek.
The player's team-mates made him the centre of their raucous celebrations, and after the final whistle, Giroud sounded awestruck at his snap achievement.
'I've never experienced that in my career and I'm proud of the whole team,' Giroud said. 'We fought like lions.
'The final stop? I made a great save at the end. (The stop felt) almost like a goal.
'I said to myself, "Go, better to go out than stay in goal”. I don’t have the automatisms of a goalkeeper but I felt it that way. Puscas massacred my arm but it's okay.
'I'm taking this shirt home and framing it.'
The forward's old Chelsea team-mate Christian Pulisic was responsible for the match's only goal three minutes before time.
And Pioli revealed that the USMNT captain might have had an even bigger role in the tie, but for Milan's height restrictions.
'Pulisic wanted to go in goal but we told him he was too short,' Pioli shared after the final whistle. 'So Oli got picked to go in'

Life is something else I stake bet player to score Girond only to see that he is now in the AC Milan goalpost as a goal stopper instead of being a goal scorer
