Forest Green manager Ady Pennock says the fracas which saw two of his players sent off after full-time at Halifax does not reflect the club's values.
Rovers lost the Conference game 1-0 and finished with 10 men after James Norwood's sending off on 83 minutes.
A brawl broke out on the sidelines after the final whistle and referee Steven Rushton showed red cards to Eddie Oshodi and Dale Bennett.
"I don't want to be associated with it," said Pennock.
The 43-year-old Rovers boss told BBC Radio Gloucestershire: "You win graciously and you lose graciously. I'm very disappointed.
"I thought it was one of our best away performances and how we've lost the game I don't know. That spoiled it at the end.
"I really don't know what happened, we'll have to look at the DVD.
"Dale and Eddie have been sent off in the changing rooms as it was assumed they'd swung a punch."
Scott Boden had put the hosts ahead after five minutes and Norwood missed a penalty before his sending off.
The defeat was Forest Green's first in 11 league matches, dating back to September.
Rovers boss Pennock went on to say he is likely to appeal against Norwood's red card - shown for his tackle on Lois Maynard.
"I didn't think it was a red card. I thought momentum took him through, but the referee is adamant he had his studs up," said Pennock.
"He runs with the ball really fast and he couldn't stop himself. We'll definitely appeal James's red card and we'll see about the other two."
