Chesterfield teenager Conor Townsend was cleared of any blame following his sending-off for an elbow in a 1-1 home draw with Morecambe.
The 19-year-old, who is on loan from Hull, was shown a straight red when he caught Will Haining in the 64th minute.
It came after Townsend had scored his first league goal with a super free-kick to cancel out Chris McCready's headed opener.
Chesterfield coach Mark Crossley said: "He's gutted, he's only had two league games and he's learning the game. If you know him as a person, you know he didn't mean to do it.
"He did catch him but I wouldn't say it was malicious because he's not a malicious player. If you do catch someone with your elbow, it could be a yellow but unfortunately it was a red. I don't think we can argue even though we know Conor didn't mean to do it.
"We are disappointed with the sending-off but credit has to go to our players that when we went down to 10 men we kept trying to win the game. Tommy (Lee) made a miracle save at the end so looking at it overall, it was probably fair."
Morecambe manager Jim Bentley agreed with Crossley's assessment that a point apiece was correct.
"I think it was a fair result," he said. "When any team goes down to 10 men and you've got 11 you fancy your chances, but fair play to them, they kept coming at us.
"It was an eventful game that was swinging both ways but I'm a little bit disappointed we didn't show enough desire to win the game when we had all our fresh legs on and pace up front.
"But you're not always going to play well and particularly at this stage of the year with a lot of games when we are stretched for bodies, sometimes it takes its toll on people."
