Mansfield may appeal against the sending-off of Danny Reet at Barnet.
The young striker saw red for a 71st-minute tackle on Nicky Bailey, but he appeared to win the ball. Giles Coke was earlier dismissed for two yellow cards.
But Stags boss Peter Shirtliff is hoping to get Reet's dismissal overturned - or he could face losing the teenage frontman for the final three games of the season.
"It wasn't a straight red card in my opinion and the referee has indicated that if we go through the proper channels he will have a look at it.
"But their player Andy Hessanthaler said it wasn't even a free-kick, never mind a sending off, and it wasn't from behind, it was a tackle from the side. He was perfectly entitled to go for the ball."
Although Shirtliff was disappointed with the way the referee handled the game, he was pleased with the response of his side as they went down to ten and then nine men.
"I can sympathise with the team but they played quite well when the two lads got sent off and they battled in search of an equaliser which they almost got.
"We had some good opportunities in the first half but we should have scored.
"We have lost two games by 1-0 now and it is not like us to not score but we have picked up 18 points in out last ten games before this so we aren't going to get too downhearted."
Stags skipper Richard Barker felt the sendings off of Coke and Reet ruined their chances.
"The referee had a poor game. I understand that referees can make bad decisions - everyone makes mistakes and the officials are pleased when players do because it shows everyone is human. But I think they are too quick to throw the cards around - that affects the outcome of matches.
"It doesn't get much harder than playing up the biggest slope in the Football League at 1-0 down and with nine men, but I think we did well."
Stags had a good chance to snatch an equaliser when Barker headed wide from six yards out. "I think if I'd have got my header on target then we would have got a point out of the game."
