Plymouth Argyle are considering an appeal against the red card given to defender Darren Purse against Hereford.
Purse, 34, was sent off for a dangerous tackle on Nathan Elder in stoppage time at the end of the 1-1 draw with their relegation rivals in League Two.
"I'll have to speak to people because I'm not sure if you appeal it whether you get another game," manager Carl Fletcher told BBC Radio Devon.
"I'm not sure it was a sending-off, but the referee seemed to think it is."
And Fletcher once again criticised referees' performances and decisions during Argyle matches.
Last week Fletcher was unhappy with the decision to send off left-back Onismor Bhasera in the 1-1 draw at Bradford.
"This is my argument all the time with referees and them making decisions.
"They've never played football before. It's two clubs bottom of the table, fighting for everything. You're going to have tackles and that was probably the first foul he's done," he said.
Purse has been an ever-present at the heart of the Argyle defence since joining on loan from Millwall in November.
