MK Dons Promoted To Championship
MK Dons can look forward to Championship football next season, after claiming automatic promotion.
MK Dons will play Championship football for the first time in the club's brief history next season after sealing automatic promotion on a tense final day of the Sky Bet League One campaign.
The Milton Keynes club, formed in 2004, began the afternoon in third place and a point behind Preston who blew their chance of a top-two finish by losing 1-0 at relegation-threatened Colchester.
Fans invaded the pitch following the win.
Karl Robinson's team ended the season in style with a 5-1 home win against bottom side Yeovil which took their goal tally for the campaign to 101 - a club record.
Carl Baker opened the scoring for MK Dons and they were 4-0 ahead by half-time after further goals from Dean Lewington (24), Darren Potter (35) and Will Grigg (39). Yeovil pulled one back as Josh Spence scored an own goal 11 minutes into the second half, but Lewington's second and the Dons' fifth restored the four-goal cushion.
Preston's first defeat in 19 league matches means it is the play-offs for them, and they will face Chesterfield in the semi-finals.
