Burton boss Paul Peschisolido has been charged with misconduct by the Football Association following an incident in the recent 1-0 defeat to Bury.
The Brewers manager has been charged with using abusive and/or insulting words towards an official as he protested against Sam Winnall's dismissal in the Gigg Lane clash.
But Peschisolido, who has until Tuesday April 19 to respond, told BBC Radio Derby that he will not appeal: "I was upset, it was a harsh red card and I made my feelings known, which I shouldn't have done."
He added: "I'm not going to appeal. I'm disappointed but what can you do?
"We'll just have to wait to see the outcome."
Burton are 22nd in the npower League Two table, three points above the relegation zone.
