Sheffield United manager Danny Wilson is expected to appeal against the red card which could rule striker James Beattie out of the League One play-offs.
Beattie was dismissed during the first-half of Saturday’s 2-2 draw with Exeter City following a full-bloodied challenge on defender James Dunne.
But Wilson, whose side now face Stevenage over two legs for the right to face either Huddersfield Town or MK Dons at Wembley later this month, said: “We’ve got nothing to lose (by appealing).
“It was a great tackle from James - yes he went through - but it was a great tackle and it’s one I’d have been proud to make.
“He won the ball cleanly and he wasn’t trying to break anyone’s leg. It was just a good hard tackle.
“The problem is that there will be four people on a panel looking at it who know nothing about football. That’s what we are fighting against.”
United, finishing behind Charlton and Sheffield Wednesday in the table despite amassing 90 points, travel to the Lamex Stadium on Friday before hosting the return at Bramall Lane a week today.
Stevenage trailed third placed United by 17 points in the rankings but are unbeaten against Wilson’s side this term.
“We‘ve got a great chance of going up and we‘ve got to try and take it,” he added. “We know Stevenage are going to be tough. They’re a good side but we are too.”
Beattie was said to be distraught after being sent-off.
“James can’t speak because he’s so gutted,” Wilson said. “And I know exactly how he feels. The lad is sat there feeling like he’s let everyone down but he hasn’t so I’m not going to castigate him. The referee has let us down.”
