Mick Harford and Stuart McCall both slammed the performance of referee Trevor Kettle after the 3-3 draw between Luton Town and Bradford City at Kenilworth Road.
Luton striker Chris Martin was red carded while Bradford boss McCall was dismissed from the touchline by Kettle, who was described by Luton manager Harford as 'incompetent.'
The Hatters boss said: "He gave a penalty which was never ever a penalty. So I can understand Chris Martin's frustration.
"I feel sorry for the fans who have got to pay money to come and see an incompetent referee and it's unjust to them. He played a big part in that result today and it was never a penalty.
"I will try to voice their opinions and just represent what they are thinking. I'm not going to skirt around the issue, because it is a massive issue.
"I'm just an honest fella and it's despicable what's gone on with the referee's performance. I'm just telling you the truth.
"We're highly-charged footballers with a lot of adrenaline there. It's two points lost in what is now a titanic battle to stay in the Football League and I feel the referee has played a big part in us not getting the three points today."
Meanwhile, Luton have let 18-year-old centre-half Harry Hogarth join Grays on work experience.
