But hey, you never know.
"Who would have thought? You just keep grinding away in men's league [hockey] and eventually you get your shot," Foster joked after he became the story of the night in the NHL.
He stopped all seven shots he faced to help the Blackhawks, who lost scheduled starting goalie Anton Forsberg during warmups and backup Collin Delia with 14 minutes left in the third period, hold on for a 6-2 victory against the Winnipeg Jets.
One of those shots came in terrifying fashion off the stick of Jets defenseman Dustin Byfuglien, who at 6-foot-5 and 260 pounds is a large man even by NHL defenseman standards. Foster, who copped to nerves but said he "blacked out" after being told he had to suit up, had a strategy.
"You just kind of brace yourself and hope for the best. He's a big man and he can shoot the puck," Foster said.
When Foster was pressed into duty, Blackhawks coach Joel Quenneville could be seen chuckling to himself on the bench as Foster passed him to head out to the ice.
"I think I would (laugh) too," Foster said. "I am an accountant by day. A few hours ago, I was sitting on the computer typing on a 10-key."
Emergency backup goalies, or EBUGs as they are sometimes called around the League, are just your average person with some hockey playing experience. They commonly attend games in case a team suffers some bad luck. But before Thursday only one EBUG had actually appeared in action, Jorge Alves of the Carolina Hurricanes, who is an equipment manager for the team and entered a game on New Year's Eve of 2016 for the final seconds.
This was quite a different situation.
"It's funny, you'd think there'd be a lot of pressure. But really, tomorrow I'm going to wake up, I'm going to button up my shirt and I'm going to go back to my day job," Foster said. "So what pressure is there for me?"
"What a moment," Quenneville said. "I had never met him before. I talked to him before the game. Nice kid. ... Opening day for baseball, but we had to go to the bullpen a couple times today. One of those interesting things you don't see very often. Both goalies played extremely well."
Foster now has a story to share with his wife and two children, ages 5 and 2, not to mention his colleagues in the office. Foster said they may hear a different version of things, however.
"I made about 30 saves in a 1-0 win," he joked.
For his efforts, No. 90 was named the First Star of the game and awarded the team's belt in the locker room.
