Notts boss Kevin Nolan revealed goalkeeper Ross Fitzsimons will sit out the trip to Cheltenham Town after being involved in a road traffic collision on Monday morning.
The stopper will stay in Nottingham following the incident but sustained no serious injuries according to the manager.
"Ross was involved in a car crash this morning so he's a bit shaken up," said Nolan.
"The protocol of making sure he's okay and that his health is the most important thing means he won't be travelling with us.
"As long as everyone who was involved in the crash is okay, that is the most important thing.
"He's just got a new car too, so he's been taking a bit of stick about that now that we know he's alright!"
Meanwhile, midfielder Michael O'Connor stepped up his recovery by playing 45 minutes in a behind-closed-doors friendly earlier this afternoon.
"Michael is on a plan we usually put the lads on in pre-season and he is at the beginning of that so we are hopeful he will come through the game unscathed without any fresh injuries," said Nolan.
"He's been involved in training with full contact for the last week or so. He has got a focus, he is working tirelessly and he is determined to make sure he comes back fitter and stronger.
"He is way ahead of schedule but we can't rush him too soon because we don't want any recurrence of the injury. It [a return to first-team action] won't be as soon as this month but we are not going to put him under any pressure.
"A few of the other lads who have not played recently are taking part too because we want them ready and raring to go for the games we have coming up in case of injuries."
