Sheffield United coach Chris Morgan has been given a one-match touchline ban and fined £1,000 after an incident in their League Cup win over Southampton.
The former defender admitted a Football Association charge of improper conduct relating to his language and behaviour.
United have accepted a charge of failing to ensure their officials behaved in an orderly fashion during the game, which the Blades won 1-0.
An FA statement said the club had asked for a non-personal hearing.
The victory earlier this month put the League One side into the League Cup semi-finals for the first time since the 2002-03 season.
But Morgan, 37, was sent to the stands after heated exchanges which followed the winning goal, scored by Marc McNulty.
After the game, Southampton boss Ronald Koeman refused to shake hands with the Blades coaching staff and accused them of a lack of respect.
"The behaviour of Sheffield United's bench, I never saw that [before]," he said.
