This was a game that never should have gone ahead.
But Jim Goodwin's battling Buddies made sure they made the most of it when it did by earning a hard-fought point against title hopefuls Celtic.
St Mirren were without an entire starting XI of first team players as a result of their mammoth coronavirus outbreak, with teenagers Jay Henderson, Dylan Reid and debutant Kieran Offord all coming into a makeshift Paisley side.
But the young hosts stood up to the challenge with aplomb, frustrating the life out of the Hoops while threatening on the counter-attack.
While Celtic enjoyed the lion's share of the possession and created the better chances, with Saints number two keeper Dean Lyness producing some eye-catching saves, no-one could deny the Paisley side deserved the draw.
And even though this was the Buddies tenth game in a row without a win, this point certainly felt like much more than just another draw.
It was a much-changed line up for the hosts, but not quite as unfamiliar as many fans would have first feared when they heard the game was going ahead.
Young prospect Offord, 17, was the only debutant on the night, filling in at right wing with fellow teenager Reid in the heart of the midfield alongside Greg Kiltie.
Henderson found himself back in the starting XI, with Lyness in between the sticks in place of Jak Alnwick.
Lyness found himself called into action early when Celtic winger Michael Johnston skipped past two Saints players on the left wing before unleashing a fierce strike that the stand-in did well to beat away.
The Hoops were perhaps unsurprisingly dominating proceedings early on and Marcus Fraser hauled down Callum McGregor as he burst through the midfield. Nir Bitton curled a powerful free-kick over the wall, with Lyness at full stretch to acrobatically tip the strike wide of the post.
Scott Tanser found himself in the referee's book early after challenging for a high ball on the left wing, before Lyness found himself called into action once again to palm away a deflected Bitton strike.
The makeshift Buddies held their own against Ange Postecoglou's men in the opening half an hour. While not making much of an impact in the final third, they were keeping the Glasgow side at arm's length.
Offord almost made a breakthrough at the right end after some determined pressing but Celtic defender Cameron Carter-Vickers just got back in time to snuff out the chance.
St Mirren were starting to make more of an impression up front and only a cynical Stephen Welsh swipe stopped Henderson from bursting down the right wing. Welsh went into the book for his troubles, with Scott Tanser's free-kick eventually earning the hosts a corner.
The Buddies almost grabbed an opener after a stramash at the back post, with the ball eventually cleared to safety for another corner.
That set piece found Charles Dunne at the edge of the box, who turned into an unlikely attacking presence as he sauntered past two Hoops defenders before firing low into the side netting with keeper Scott Bain scrambling.
St Mirren grew in confidence as the first half drew to a close, with Celtic unable to find a way through the stubborn home defence.
The hosts returned unchanged as they looked to keep Postecoglou's side at bay, unsurprisingly given the young options they had on the bench.
Johnston had a close-range early snap shot that Lyness did well to hang on to just after the restart, with Owen Moffat blazing wide shortly after as the Hoops looked for a quick breakthrough.
McGregor fizzed a half-volley over the bar as Celtic continued to press, with Rogic also blazing over from a promising position.
McGregor curled a long range effort goalwards that Lyness held at the second attempt, before the keeper tipped over the bar with his foot as Celtic continued to batter on the door.
St Mirren were refusing to yield and looked like opening the scoring when the impressive Henderson did brilliantly on a counter attack, eventually beating his man before laying into the path of Curtis Main. His low shot was held by Scott Bain.
Celtic were inches away from finally opening the scoring when McGregor got to the byline before fizzing in a cross that Liel Abada just couldn't tap home.
Substitute Josip Juranovic curled a free-kick just wide of the post as the Buddies continued to hang on, with Goodwin roaring on his battling troops from the touchline.
And despite a late onslaught from Postecoglou's men, St Mirren stood firm to earn a well-earned point that most Saints fans would have bitten your hand off for before kick-off.
