A late penalty from Che Adams earned United a point in an entertaining fixture at Fleetwood.
He took responsibility after Ryan Flynn had been fouled, whilst Matt Done was credited with a deflected effort in the first half.
The game had effort cleared off the line, the ball hitting the woodwork and a red card too in the sunshine on the coast.
Basham captained United as chief Adkins made four changes, some enforced. Baptiste, Hammond, Flynn and Calvert-Lewin all started, they took the place of McEveley, Collins, Coutts and Sharp, the latter was ill and unable to travel. On the bench, 19-year-old Whiteman was joined by fellow Academy graduate, 18-year-old Irish left-back Kelly.
United made the brighter start and most of attacking intent was centred around Adams, his diving header flew over the crossbar on seven minutes following an inviting cross by Brayford.
Adams tamely shot at goalkeeper Maxwell soon after and he was the intended target of a Cuvelier cross on 20 minutes but the ball was cut out at the expense of a corner. Fleetwood's first chance came as the result of a break from a Blades corner but Hunter curled wide of Long's left post.
United grabbed the lead just before the half hour mark. With space in his left wing-back role, DONE's delivery appeared to take a take a deflection but he was credited after the ball dropped into the corner of Maxwell's net.
The lead, however, lasted less than 90 seconds. A cross from the right saw HUNTER lose his marker and place a header into the top corner, beyond Long's reach.
Later in the half Adams was crowded out and Cuvelier produced a great block, whilst there was a penalty appeal when Calvert-Lewin won possession and looked to be pulled down by Ball just inside the box but referee Boyeson was not interested.
Fleetwood, meanwhile, finished the first half with ten men; Davis left the field with a head injury and did not re-appear for the second half despite, no doubt, extensive treatment. He was replaced and there was also a Blades change at the interval - Coutts taking over from Cuvelier.
The start to the second half was entertaining, with chances at both ends. Ryan shot wide and then Calvert-Lewin held off Jonsson but his half-volley was just over.
Fleetwood then hit the crossbar and a post in the same move, Burns unable to convert Ball's cross and then Flynn's shot wide after having the time to control a pull-back from Adams.
Adams got the better of Nirennold but shot tamely at Maxwell and Fleetwood took the lead with the next attack. Ryan's inswinging free-kick saw NILSSON rise highest and his header clipped the post before creeping into the net.
The chances continued, at both ends. From another Fleetwood free-kick, United half cleared but Ball's shot was on target before Edgar blocked and then Baptiste headed wide a Done corner.
For the final 15 minutes the pressure was coming from the Blades as the home side attempted to slow down the play. From Done's free-kick over the defence, Hammond connected but could not find the target and then from a corner both Baptiste and Hammond won headers before Maxwell claimed the ball under his own crossbar.
From a Flynn corner, substitute Sammon's header was cleared off the line by Burns and late on Fleetwood's Haughton, only on the field for 17 minutes, was sent off for two bookable fouls.
As five minutes of added time was announced, Flynn's shot was blocked and then the Scotsman won a penalty from Bell. ADAMS took responsibility and beat Maxwell, despite the goalkeeper's gamesmanship in stalling at every opportunity.
There was still time for Adams to sting the palms of Maxwell again and after a frantic end there was a disallowed goal. From Done's corner, Hammond was adjudged to have fouled Maxwell before Brayford touched into the empty net and the final whistle followed soon after.
