Sheffield United boss Kevin Blackwell could face censure for angry comments about referee Peter Walton following his side's FA Cup exit at Hull on Thursday night.
The Blades were beaten 2-1 in their fifth round replay at the KC Stadium after Hull benefited from a controversial own goal by Kyle Naughton. England Under-21 defender Naughton handed Hull a 24th-minute lead when his errant header was ruled to have bounced over the line after crashing off the crossbar.
"We have lost a game we haven't lost," he said. "The first goal isn't a goal."
Replays offered no definitive proof the ball had crossed the line and Blackwell thought the Blades had been on the end of a poor decision.
Blackwell added: "They can stand here and try to persuade me until they are blue in the face, but that isn't a goal.
"The official has made a decision and he is not 100% sure - that is what is the disgrace.
"Somehow we have lost and I don't know how it is."
The Blades managed to claim an equaliser through Billy Sharp but Peter Halmosi settled the game in Hull's favour after 56 minutes. There was further controversy, however, with United denied a penalty after Sharp was apparently tripped by Kamil Zayatte.
Blackwell added: "If a manager and players get it wrong, you get sacked or dropped. If officials get it wrong they get a game the following week.
"I think when officials have as poor a game as that they should be made to face the reporters, as we are, and ask why those decisions they are made.
