SHEFFIELD United fell to MK Dons who finished the match with 10 men. Alan Smith scored his first goal in five years to settle the contest.
Dons had made the much brighter start and in the 16th minute they took the lead.
Bowditch forced Lowton to concede a corner which was swept in by Williams.
Lewington headed the ball on and SMITH stooped to head home before standing - arms aloft - in front of United’s fans. It was his first goal in five years.
If manager Danny Wilson, watching arms folded on the touchline, hoped Smith’s goading would provoke an immediate response he was disappointed.
United appeared flat and subdued until Lowton’s driving run from McDonald’s pass saw Williamson win a 21st minute corner.
A potential turning point came in the 66th minute as Powell collected his second caution for dragging back Doyle.
MK Dons responded by introducing Chadwick and Ibhere for MacDonald and Smith.
On 77 minutes Beattie came on with Porter making way.
As United grew in stature and started to ask questions of MK Dons’ defence, Doyle just mis-timed a first time shot which duly flew straight into Martin’s arms while, at the other end, Simonsen palmed away an effort from Ibehre as the hosts looked to pounce on the break.
United finished the contest well on top with Lowton heading wide before Martin was booked for time-wasting.
But, in the 86th, Ibehre struck the post again on the counter-attack.
Then, in the 90th minute, Beattie was inches away from the equaliser after lunging - but failing to connect - with Lowton’s cross.
