United's U18s got a deserved point from Saturday's six goal thriller against Barnsley at the Oakwell Academy.
A last-gasp penalty from Keegan Burton rescued the Blades, who named a particularly young side against the Tykes, a share of the spoils, with Oliver Greaves also netting a brace.
Lead Coach Derek Geary was pleased with the result, especially given the youthfulness of his squad.
He remarked: "With the U23s in action a lot of the regulars featured for them, meaning some U16s, college lads and some of the players who haven't played as much this season got an opportunity.
"In the end we got a point which was the least we deserved. With a bit more luck and composure, in addition to cutting out the individual errors we could have won the game."
United started brightly and took the lead in the 5th minute. GREAVES applied the finishing after he followed in Brown's cross from the left. And moments later a header from Hawkes went just over.
Barnsley responded promptly and levelled in the 17th minute, following pinball in the penalty area from a corner the ball was forced home from close-range.
Ten minutes before the break the home side went in front, despite the best efforts of Perryman, who did well to save the initial shot before being powerless to save the rebound.
The Blades were quickly out of the blocks after the interval with Greaves and Burton both going close either side of the hour, although at the other end, Perryman was required to keep the game at 2-1.
With 13 minutes remaining the Blades made their pressure count, from a good pass from Burton, GREAVES checked back onto his right foot before shooting into the top corner.
In the 89th minute though, the game looked to have cruelly gone against United as Barnsley scored with a low shot.
But United had the final say to get a draw as BURTON netted from the penalty spot in the final minute of added time after he had been upended when advancing towards goal.
Blades: Perryman, Portman, Brown (Potts 74), Cummings, Ferguson, Cantrill, Hawkes, Allerton, Ford, Greaves, Burton.
Unused: Holmes, Warhurst.
