Scott Malone's strike ensured League Two survival for Burton as they drew with Southend.
The Shrimpers took an early lead through top scorer Barry Corr's header from Ryan Hall's corner.
Malone, who was on-loan at Southend last season, levelled for the Brewers after a fine run and finish.
Jacques Maghoma was sent off for the visitors after an altercation with the home fans before Lee Sawyer saw red for the hosts for two bookings.
Player/coach at Southend United Graham Coughlan told BBC Essex:
"I feel if we played with a bit more tempo and urgency we may have won out. But it was a typical end of season game, both teams had little to play for apart from pride.
"You could see at the end, they were delighted with the points, all-in-all it was a fair result.
"We took our foot off the pedal and they got themselves back into the game."
Burton manager Paul Peschisiolido told BBC Radio Derby:
"I'm relieved. It's been a long three months, when you consider we've played 27 games in three months, that's more than half a season, that's some going.
"The lads have given me everything they've got and there's a very happy dressing room right now, me included.
"We've had a good run, these last five games we've performed fantastically well against all the odds."
