Southend stun leaders Burton
Burton missed the chance to move seven points clear at the top of League One as they lost 3-1 at Southend.
Nigel Clough's side had the chance to respond to Wigan's weekend win with a victory of their own, but were denied by Phil Brown's men who have their own promotion aspirations.
Anthony Wordsworth put Southend ahead seven minutes in, but Stuart Beavon levelled a minute before the break.
Tyrone Barnett then restored Southend's lead in the 63rd minute before David Mooney's last-minute clincher.
Wordsworth's opener came when he moved in on a blocked Jack Payne shot.
Burton went into the break level, though, as Beavon's strike was deflected past Daniel Bentley.
But Barnett got Southend ahead again when he cracked a fine strike past Jon McLaughlin and Mooney rounded things off on the counter.
Southend are seventh on 50 points after this win, two behind Coventry who occupy the final play-off place.
