Nigel Clough has revealed Febian Brandy will be disciplined 'in-house' following his red card at Shrewsbury Town.
The Blades boss says Brandy must learn from his ill-discipline, which cost United the opportunity to take anything from game at Greenhous Meadow.
Following Brandy's second dismissal of the season, Clough said: "We have no complaints at all about the red card, you simply can't raise your hands like Febian did.
"It will be pointed out to him that his reaction was unacceptable and it costs us the opportunity to take anything from the game, which is frustrating. He will be disciplined in-house.
"I don't care how frustrated he was following the two tackles, you don't react like that.
"Even if he had been kicked from pillar to post you get up and go again, you can't just lash out at the opposition."
Clough also explained in full detail the withdrawal of Neill Collins at the weekend, in addition to praise the impact Aidy White and Shaun Miller had on the Blades, with the latter edging ever closer to a first-team start, following a serious knee injury.
The Gaffer added: "Neill (Collins) had a swelling, bigger than a golf ball above his eyebrow following a clash of heads.
"We tried draining it at half-time, but when that didn't work it was too risky to let him continue.
"Aidy (White) did well and his performance pleased me, as did Simon (Lappin) in midfield.
"Shaun (Miller) is getting much closer to full fitness and after another full week's training he will be in contention to start at Colchester in the FA Cup."
