Sheffield United's Under 23s were denied a second 3-2 win on the bounce with the last kick of the game as Bolton Wanderers came from behind at the death to snatch a point.
It was a game the Blades should have been out of sight in despite falling behind early on. A combination of slick passing football and plenty of chances created ensured a 'what if' night for United who conceded after going down to 10 men in the final minutes after Harry Sheppeard had to go off injured.
It took United 15 minutes to get going and when they did they were already 1-0 down after a neat passing move from the hosts ended in Ronan Darcy volleying home from just inside the box.
But once they settled the Blades dominated the rest of the half and equalised after a nice move of their own which ended in captain Reece York cutting in from the left and firing home into the far corner.
The momentum firmly swung United's way and it was Jake Young who went close on two occasions in a matter of minutes, first forcing a save at the near post before curling an effort just wide as the visitors looked to turn the game around.
Young did finally find the net soon after when he went on a mazy solo run through the middle and found the near post corner of the net with a low effort to make it 2-1.
George Broadbent was denied by a great block and a save in a matter of seconds but United didn't manage to build on their dominance and Bolton punished them just before the break when Eddie Brown headed home after a shot had come back off the post.
10 minutes after the break the Blades were back in front. The trialist up front showed persistence to harry a defender after a poor kick out from the goalkeeper, nicking the ball off the centre-back and slotting home into the corner.
Bolton though came on strong as the game wore on. Jordan Amissah had to be alert to push away a powerful effort before the hosts missed a huge chance with two minutes to go with Senior sliding the ball just wide at the back post.
Substitute Sheppeard then had to go off well into stoppage time after a nasty tackle from behind stopped a United counter, and with United having used all three substitutes they had to play the remaining added time with 10 men.
It cost them dearly when the last kick of the game was converted by Callum King-Harnes who fired home after running onto a cross from the left to deny the Blades victory at the death.
