SHEFFIELD United fought back valiantly to gain at point at Scunthorpe despite finishing with only nine men.
Michael Doyle saw red early on, and was followed by Ryan Flynn in the second half. United trailed to a Leon Clarke goal yet Neil Collins equalised the ex-Owls striker’s effort late on to put the seal on a Herculean effort by the Blades.
On 16 minutes United were reduced to 10 men.
Referee Rushton has not been shy to produce red cards this term and he had no hesitation in dismissing Doyle following a tackle on Grella deep inside Scunthorpe territory.
Collins collected the armband and Cofie assumed a deeper lying role as Wilson plotted his response.
McDonald again emerged as a key figure in Danny Wilson’s midfield.
The contest’s abrasive undercurrent was in stark contrast to the Scot’s slick play.
Just under the hour sub CLARKE used only his second touch of the ball to steer Duffy’s cross back across goal and inside a despairing Howard’s far post.
The former Wednesday marksman’s intervention saw the match finally played at pace.
Only the width of the crossbar prevented Collins from levelling in the 63rd minute after climbing highest at Flynn’s corner.
Flynn collected United’s second straight red card of the match for a high foot on Duffy as they contested a bouncing ball.
With eight minutes remaining, Miller entered the fray at Cofie’s expense and, seconds later, COLLINS did restore parity by converting McMahon’s free-kick.
Cue jubilant celebrations among the 2,232 away fans and, at the other end, a superb save from Howard to deny Walker.
