Although the manager now expects Garry Kenneth to be fit for the game, he will be without Tom Parkes, who picked up a red card on Tuesday night, and Adam Virgo is also injured.
Mark said: “Adam Virgo is injured and I feel sorry for him, as he has come in for a lot of undue criticism, but he is not going to be available for Saturday.
“Garry Kenneth who took a knock on the knee on Tuesday is going to train this morning, so hopefully he will be fine for Saturday.
“Derek Riordan is training this morning, but he hasn’t trained with us until this morning, so I think it is unlikely we are going to star Derek on Saturday.
“Fabian is training this morning and I expect him to be available for the weekend.”
Mark is still disappointed with Tom Parkes’ dismissal.
He said: “We have the suspension now to the very stupid Tom Parkes. After he was booked on Tuesday I told him whatever you do, do not get sent off.
“For him to foolishly get a second yellow card is beyond comprehension, so now we have to make a decision as to we play as our second centre half alongside Garry Kenneth.
“I had a word with Tom after the game on Tuesday, it was the first thing I said when we got into the dressing room, and I have just given him volley just now.
“I am still upset and angry that he was foolish enough to let us down like that.”
The manager does have other options at the back. “At the end of the day we have a game to play and we will play it.
“If Kenneth wasn’t fit we have Seanan Clucas who has played centre half for the U21s so he is an option, we can play Patty and Lundy as centre halves.
“We will have two centre halves, we won’t play without centre halves on Saturday, but I suspect Garry Kenneth will be fit.”
And Mark is not happy with the unpredictability of his side in recent weeks.
He said: “I am starting to think I have a squad who are almost schizophrenic.
“One week they turn up like they did during the first half on Saturday, performing in a way that was everything I dreamed it would be in terms of passing and movement and getting a couple of goals.
“The second half, especially the first 20 minutes, was a reversal where they seemed to disappear inside themselves, and it was the same the other night.
“We lost a goal and there was a change and we became individuals rather than a unit that has got us the recent results.
“A lot of them are young lads and they are not handling those situations well, that is why we need experience around them.”
Accrington have lost their last four games in a row and look set to lose their manager Paul Cook to Chesterfield.
Mark said: “I was not aware of their managerial situation. We have been looking at the team, looking at their players and looking at videos, as I want to know as much about them as I possibly can, but the managerial situation does not affect how the 11 players are going to play.
“The other night I question my own preparation in a sense that maybe I didn’t quite give them enough credit.
“I thought that if we went there and played as well as we can we would beat them. On Saturday I am going to pay a lot more attention to Accrington.
“They will be desperate for three points, the reality of it is they are struggling, and we have to make sure that we don’t go there and be the team that turns it around for them and end that run.
“We have to go there and try and be a lot more compact and a lot tighter than we were the other night and not concede goals.”
