As such, Chicago desperately needed someone - anyone - to fill the role of an emergency backup. He was the NHL's best goalie for 14 minutes of his life. But they rarely take the ice; before Foster, the only other EBUG to get NHL ice time played for the Carolina Hurricanes in the final seconds of a game in 2016, according to NHL.com.
"I was probably a block away, so moments before warm up, roughly give or take", said Foster when he was told he would be the official backup for the Blackhawks. "You just kind of black out after that".
After the game Foster was awarded the MVP both on the ice and again in the locker room by his teammates. It was nothing short of unprecedented, but boy did Foster ever make his chance of a lifetime count.
He stopped all seven shots that he faced in 14 minutes of action as the Blackhawks won 6-2 over the Winnipeg Jets.
"That's something you'll never forget", Foster said during an entertaining postgame interview.
It worked out for the Blackhawks, as Foster saved seven shots in what became a 6-2 win. They chanted "Foster" a number of times.
But how did the father-of-two and recreational player end up trending on Twitter and stealing the spotlight from fellow Blackhawk Brent Seabrook, who played his 1,000th-regular-season game that same night?
"What a moment", Blackhawks coach Joel Quenneville said with a chuckle. He was asked what he would tell his co-workers about his unexpected debut - assuming he showed up for work on Friday, and really, wouldn't you call in "sick" if you were him? The guys played for Foster like he was their starting goalie in Game 7 of the Stanley Cup Finals. "From my perspective, this is a dream regardless".
Foster reportedly told the Blackhawks' equipment staff as they took his bag out of his vehicle when he arrived at the arena: "Holy crap, I hope I don't have to play tonight". "Just a ton of fun".
Two years in the NAPHL, followed by two years in the NAHL with the Amarillo Bulls, helped Chicago Blackhawks goalie Collin Delia get to the point where he made and won his National Hockey League debut on Thursday night. He would get a bite to eat, enjoy the game in the press box, then head home.
And the story his buddies on his amateur beer-league hockey team will hear?
