Former Spireites striker Kristian Dennis’ scored the winner as Chesterfield were knocked out of the FA Trophy following a 1-0 loss to Notts County.
Both sides were heavily rotated. John Sheridan made seven changes, while Neal Ardley made eight alterations.
Just 12 minutes in, Zoumana Bakayogo prevented County from going a goal down when he cleared Joe Rowley’s strike off the line.
The Magpies had a chance of their own not long after, when Shwan Jalal was forced to palm Dennis’ effort from outside the area away from goal.
Rowley was the danger man again in the 15th minute when County keeper Sam Slocombe tipped his header over.
Neil Ardley was left with no choice as he made his first two changes. James O’Brien and Slocombe were forced off with injury, while Michael Doyle and Jake Kean came on to replace them.
Just before the break, Rowley once again was close to finding the back of the net. The 20-year-old saw his half-volley come back off the crossbar.
Despite creating plenty of chances, the Spireites couldn’t find the back of the net, so both sides went into the second half on level terms.
Sam Osbourne nearly broke the deadlock on their hour mark when Jalal was forced into a low save to keep the strike out.
But Osbourne provided the assist when he attained possession from the Chesterfield midfield and provided the low ball for Dennis to tap it into the net.
Despite an impressive first-half performance, the Spireites couldn’t find the back of the net and their FA Trophy campaign ended at the First Round.
