In a game that seemed destined to come down to the last second, it was a strange play by the Stampeders that ensured exactly that.
After kneeling twice in an effort to run the bulk of the final minute off the clock, Henry Burris found himself facing third down and 13 with seven seconds remaining.
Instead of scrambling backwards from his own 41-yard line to kill the remaining ticks, he dropped back and threw a Hail Mary-type bomb that landed four rows into the stands.
Problem being, it only killed six seconds, giving the Lions one last chance to throw a Hail Mary of their own in a 22-18 game.
"That was messed up," said Burris, one of many Stamps who walked to the sideline stunned they'd goofed the simplest of plays.
"I thought 'Oh no' ... I didn't know they added an extra second."
From the time the Stamps ended their previous play to the time they returned to the field following a timeout, the officials asked the clock operator to change the time remaining from six seconds to seven.
"I was thinking a six-second throw would get the job done as long as you get it in the stands," laughed Burris afterwards.
"If I would've known it was seven seconds, I would have thrown it further downfield. As soon as I released the ball and saw the seven seconds ticking I'm like, 'Are you kidding me right now.' "
As it turned out, defensive back Milton Collins was able to bat down Buck Pierce's Hail Mary in the endzone, but not before 35,000 fans and one fuming coach suffered minor heart palpitations.
"The play is designed to take six seconds off the clock -- you go back and throw it as high and far as you can out of bounds and the game is over," explained John Hufnagel.
"When we called the timeout, there was six seconds left. We call the play and we're breaking house and they add a second.
"If there was seven seconds left, I would never have done that play."
Thankfully for the Stamps, the defence did what they did all day -- came up big when it mattered most.
"They did a great job sealing the deal," said Burris.
"I'm thinking, 'at least somebody let me know what's going on.' "
