Conor Chaplin scored a stoppage-time winner as Portsmouth stunned Middlesbrough to boost their Championship survival hopes and deal a hammer blow to the Teessiders’ automatic promotion bid.

Chaplin struck in the seventh minute of time added on from Adrian Segecic’s corner to score from Portsmouth’s only shot on target at the Riverside Stadium.

Middlesbrough have slipped to fourth place in the table and are three points behind second-placed Ipswich, having played two games more.

Chaplin’s late, late winner, meanwhile, hauled Portsmouth back out of the bottom three and they are a point clear of Oxford with a game in hand.
