Notts will be without both Jason Beardsley and Ian McParland for Monday's televised clash with Brentford.
Manager, McParland faces a two-match touchline ban for the use of 'abusive and/or insulting' words before being ordered to the stands in County's 2-2 draw with Shrewsbury Town at the end of August.
The ban will come into place on Monday, meaning that he will have to watch from a distance as his side take on the Bees and then Macclesfield Town on Saturday.
Beardsley, on the other hand, has sustained a thigh injury that will keep him out of action for around a month.
He will return to Derby County to receive treatment on the problem, several weeks after it was first sustained.
McParland explained the situation to the Nottingham Evening Post, saying: "Jason picked up an injury a few weeks ago and he should have had a rest.
"It was a dead leg and he went and got a bit of ice on it and the physio was asking if he was all right.
"He said he was fine. He is a young lad and he is one of those players that doesn't want to miss training.
"He does not want to miss a game - he wants to play in every one.
"There are not a lot of players like that about these days.
"He should have reported it and told us he needed a few days off but that is not him. He will learn from that.
"Hopefully he can get back as quick as possible and be up for selection again, because he has been doing marvelously well for us."
Adam Tann, who played 90 minutes in last weekend's 2-1 win against Port Vale will now continue to fill in at right-back with the aim of retaining the spot when Beardsley returns.
In more positive news, both Adam Nowland and Stephen Hunt are on the verge of comebacks.
McParland revealed that Nowland could return to training over the weekend, and Hunt is around two weeks away from overcoming his long-standing groin issue.
