Jake Ford's stoppage-time equaliser saw United maintain their unbeaten run in 2017, with a deserved draw on Saturday.
Derek Geary's youngsters, who have already beaten Birmingham, Hull and Nottingham Forest since the turn of the year, needed Ford's late strike and a goal from defender Sam Graham to salvage a point against the Trotters who twice led in an entertaining encounter at Shirecliffe.
The home side had a good chance inside the opening ten minutes, with Stewart heading straight at the goalkeeper from a promising position after an inviting cross by Greaves.
But it was the visitors who took the lead in the 28th minute. SAMIZADEH pounced on a cross from White and slotted home from close-range.
From that point until the break, Wanderers seized the initiative and thought they had double their lead moments later but the officials ruled the ball hadn't crossed the line after a shot hit the underside of the crossbar.
The Blades equalised two minutes after the restart, with the linesman perfectly placed to indicate the ball had crossed the line from a corner following a header and subsequent scramble. GRAHAM was credited with the goal.
With the scores level, both sides were positive and tried to win the game. For the Blades, Cummings was a threat from set-pieces, whilst on the break the visitors looked dangerous.
And in the 85th minute it looked like Bolton had snatched the points, as JONES-GRIFFITHS applied the finishing touch past Warhurst following a swift counter attack.
But only 15 seconds remaining of added time remaining, United levelled for a second time to snatch a point. Greaves was denied when a goal looked certain, but from the resulting corner FORD fired towards goal from the edge of the penalty area and with the aid of a deflection the ball nestled in the bottom corner.
Blades: Warhurst, Charlesworth, Cantrill, Graham, Cummings, Ford, Greaves, Doherty, Stewart (Portman 62), Hallam (Hirst 45), Parkhouse (Burton 72).
