Derby County have suffered a 1-0 defeat at Sheffield Wednesday to miss out on the League One playoffs.
The Rams went into the final game of the season holding a two-point lead over Peterborough United, with goal difference ensuring that a point was realistically required at Hillsborough.
However, as Peterborough went in front during the early stages at Barnsley, Derby were second best versus Sheffield Wednesday and conceded just before the break through a Michael Smith penalty after Curtis Davies had been sent off.
Jack Taylor doubled Peterborough's lead against Barnsley, adding to Jonson Clarke-Harris's opener, and Derby were unable to find the equaliser that they needed to avoid missing out by a solitary point.
