Jayden Wareham's header earned relegation-threatened Exeter City a 1-0 win at AFC Wimbledon and extended the home side's winless run in League One to nine games.
The Dons thought they had levelled in the second half, only for the effort to be ruled out, and could not find a way back as Exeter saw out a hard-fought victory.
Wareham Rises Highest
Wareham rose highest to nod Ilmari Niskanen's superb cross into the bottom-right corner to score his seventh league goal of the season in the 37th minute.
