Oldham manager Paul Dickov was unhappy with the decision to send off Bradley Diallo in the 1-1 draw with Huddersfield.
Diallo was shown a straight red card for his late tackle on Oscar Gobern 14 minutes from time.
Dickov claimed: "Their lad went down screaming like a baby.
"It's possibly a yellow but there was no malice and a sending-off was harsh."
Oldham debutant Shefki Kuqi out them ahead after six minutes but Town grabbed a point through Anthony Kay's volley.
