FA disciplinary chiefs are reviewing the Danny Schofield dismissal and may extend the three match ban he starts against Walsall at the Galpharm tomorrow.
The 24-year-old, who apologised to his teammates and manager Peter Jackson at the training ground yesterday, is alleged to have headbutted and spat at Morecambe's Michael Howard in Tuesday's LDV tie.
The FA have requested video evidence following referee Russell Booth's report and Jackson - who is without Andy Booth and Rob Edwards tomorrow - explained:
"Danny has apologised, it was completely out of character for him and he has admitted it was a stupid mistake.
"He has been dealt with by the referee and the club, but now the FA are having a look.
"There is obviously a question mark about a longer ban, but the video doesn't show the whole incident.
"It goes back as Danny is being sent off and, while he does spit as he walks away, he spits downwards in my opinion and not in the direction of the Morecambe player."
While Schofield, Jonathan Worthington and Efe Sodje are suspended tomorrow, Jackson has Andy Holdsworth and Tony Carss fit again, although the latter will be on the bench.
Junior Mendes is favourite to partner Pawel Abbott up front against a fourth-bottom Walsall side coached by Iffy Onuora and who have used 23 players so far this season.
Ian Gray returns in goal and Jackson said: "We've got the same seven points home and away this season and, if we are going to be serious contenders, we need to make the most of home advantage by keeping clean sheets and going on the attack like we can.
"Walsall can't be given any incentives. We have to be tight and aggressive to beat them."
