Portsmouth manager Michael Appleton felt referee Carl Berry lost control of the game after seeing his side lose 1-0 to Oldham following a bizarre second half at Fratton Park.
The Latics claimed all three points after Jonathan Grounds' cross-cum-shot slid into the Pompey net after taking a deflection off debutant Johnny Ertl after 59 minutes.
Both sides were then reduced to 10 men in a cloud of confusion four minutes later. Jordan Obita was dismissed for Portsmouth for an apparent elbow, before Cliff Byrne also saw red.
However, Oldham's sending off could be rescinded due to a case of mistaken identity, as it was Connor Brown who was involved in the tussle with Obita.
Appleton said he did not see the incident, but he was far from happy with Berry's handling of the contest.
"I wasn't sure what was going on, but I know players from both sides were confused," said Appleton. "I think the referee lost the plot a little bit and lost control of the game. It became a little bit of a farce at times.
"I just said to him that I thought the game was a little bit too big for him. He seemed to lose control in a big, big way. It was all there for everyone to see. It's not something I'm making up. I think it was a tough day at the office for the referee.
Oldham manager Paul Dickov hopes to see Byrne's red card overturned after speaking to Berry and his team of officials following the final whistle.
"I think they realise it was a mistake, so hopefully common sense will prevail," said Dickov.
"It's a strange one for me because in my short time as a manager I've never had to appeal."
