Eamonn Dixon started the day with plans to watch the NFL Super Bowl on TV from his home in San Francisco, but finished the day in the stadium holding the ball after the winning field goal.
Mr Dixon, from Melbourne, lived out every NFL fan's dream when he caught the ball Kansas City Chiefs kicker Harrison Butker booted through the goal to win one of the biggest yearly events in world sport.
As he clutched the ball to his chest, Mr Dixon was grateful his days playing Australian Rules Football as a kid gave him the skills to ensure he didn't make a meal of his big moment.
"Big thanks for Fitzroy Vickick, back in the day, as the real legends here," Mr Dixon told ABC Radio Melbourne from his hotel room in Phoenix.
"I was just trying to film it, so I had the history of the moment on my phone, and then — all of a sudden — it was just coming towards me. It was just very surreal, the whole thing."
Mr Dixon — who works in advertising — had already achieved a major career goal earlier in the day when a TV spot he'd worked on for months aired during the broadcast of the game.
"That was a real bucket-list moment for me, let alone what happened at the end of the game," he said.
The former Melbourne man was only a last-minute attendee at the game, after a client rang to offer him a ticket earlier in the day.
However, Mr Dixon lives in San Francisco, California, and the game was being played in Arizona.
In the end, he said, he made the right call in booking a flight and getting to the stadium.
"I raced to the airport and raced to the stadium and got there just in time for the start of the game and four quarters later I was holding the ball," he said.
Mr Dixon said it was a miracle the ball even made it into the stands, as a net was raised behind the goal to catch kicks, but this one sailed over the top of the net and into his arms.
He said "all chaos broke loose" once people in the stands realised such a significant piece of football history had just landed in their midst.
"One of the security guards said to me: 'I'd get out of here with that if I were you'."
Mr Dixon said he would take the ball back home for some photos with his children, but could be open to offers for it after that.
"I've had a couple of people reach out to me already and say, 'Hey, if you're thinking about getting rid of that let, me know and I might be able to find someone who'll pay you for it'."
He might expect a call from the winning goal-kicker, Harrison Butker, who will no doubt be keen for a keepsake from the biggest moment of his sporting career.
