Gavin Strachan is set for a month on the sidelines after picking up yet another hamstring injury in the win over Exeter City last weekend.
Moments before pulling up, the midfielder had slid onto a Myles Weston cross to net the decisive goal in the 2-1 triumph.
The ex-Peterborough man had become a regular in the starting-11 since his return from his previous lay-off six-months prior.
Notts' boss, Ian McParland expressed his sympathies when speaking to BBC Radio Nottingham earlier today.
"It's a blow because I think he was doing very well and I was delighted when he got the winner," he said.
"It's soul destroying for Strach but he keeps going. He's as honest as the day is long and I feel for him."
He also added that he does not expect to recruit any more midfielders as a result of the disappointing news, explaining: "I would like to think we could get by but we're always having a look."
Fellow midfielder, Richard Butcher is expected to make a comeback from his foot problem at around the same time.
