Harford took over last Thursday and oversaw the 1-1 draw at Sunderland on Saturday, in which Hylton was shown a straight red card after a coming together with Jack Baldwin with 20 minutes left to play.
The club looked at the possibility of appealing the decision, but the video evidence was not conclusive enough to suggest that referee Lee Probert had made a clear mistake when dishing out the card.
Harford said: "We were debating it, long over the last few days whether to appeal. It's got to be a clear error by the referee to get Danny off this one and it's just not conclusive in any way. All the angles we've looked at, it's just not conclusive and we don't want to run the risk of Danny getting an extra game for a frivolous appeal, so we just believe it's the best way forward and we'll have to cope without Danny. He's a key player for us and he's going to be a big miss.
"We will adjust, we will adapt, the window is still open, so there's an opportunity hopefully to bring in a player, a striker or another position. So we will try and bolster the squad that way. We've got a list of candidates, whether it's a loan or a permanent, I couldn't answer that I am afraid.
"Danny was distraught on the coach on the way home, he was distraught. He kept telling me that it wasn't intentional and I fully believe him. I had a chat with Danny this morning and he's very, very disappointed, not in himself, just in the decision.
"I've been in that position loads of times and you back in, you put your arms up. He hasn't thrown an elbow, it's a straight arm, the lad's come on top of it, the lad's got straight up. Danny has actually broken his nose in that collision, somehow he came out worse."
Mick will be directly involved in helping select Nathan Jones' successor, with the former Hatters forward saying he enjoys his role as Chief Recruitment Officer and fully intends to return to that in the near future.
"I am privileged that Gary and the board have asked me to be involved in appointing a new manager," Mick continued. "We've had numerous emails, contacts. But I think the best part of it is, it's concise, we're doing the right thing.
"I don't want the job, I think we should bring a new manager in. so there's no uncertainty in that, I don't want 'if Mick wins a game, will he get the job?', none of that, we will bring a new manager in.
"Gary and the board will take as long as it takes to get a new manager and hopefully we get the right man. I want to concentrate on the role [of Chief Recruitment Officer], that I have been given at the football club, which I thoroughly enjoy and I see that as a career path for me at the moment."
