Burton secured their spot in Sky Bet League One for another year and Wigan took another step towards safety after a 1-1 draw at the DW Stadium.
The visitors took the lead after 16 minutes when Joe Powell curled a brilliant free-kick over the Wigan wall.
But Wigan raised their game and were back in it eight minutes before half-time, when Lee Evans' corner was headed home by the in-form Will Keane.
In a game of little goalmouth action, one more goal was always likely to prove to be the winner.
But Wigan goalkeeper Jamie Jones hardly had to make a save worthy of the name.
At the other end, on-loan Aberdeen midfielder Funso Ojo smashed a goalbound effort straight at a Burton defender.
Then, in stoppage time, an Evans corner was headed down by Joe Dodoo into the path of George Johnston. But from the penalty spot, the on-loan Feyenoord defender lashed his effort high and wide of the target.
