Chesterfield’s six-game unbeaten run was ended by defeat to fellow National League play-off chasers Bromley.
Michael Cheek gave Bromley the lead after 19 minutes, slotting past Chesterfield goalkeeper Grant Smith after being sent clear by Billy Bingham.
Captain Laurence Maguire, brother of Manchester United and England defender Harry, equalised in the 74th minute, collecting the ball from a corner and scoring his first goal of the season.
However, with five minutes left, Joseph Kizzi latched on to a Frankie Raymond ball to head home the winning goal.
A third straight win moved Bromley level on points with Chesterfield, who hold the final play-off spot on goal difference.
Meanwhile, Spireites striker Akwasi Asante faces nine months out after rupturing his Achilles.
