They've gone goal crazy at the Riverside. Mark Viduka converts Andrew Davies' cross from the right and surely Boro have this in the bag now.

1936: With less than 10 minutes to go until kick-off between Barnsley and Southend, there is hardly a fan in sight at Oakwell.
1931: Team news from the Riverside: Teenage full-back Seb Hines makes his Boro debut, with Emanuel Pogatetz and Andrew Taylor out. Hull are without former Boro star Nicky Barmby so Nicky Forster starts.
1909: Team news from the City of Manchester Stadium: Bernado Corradi gets a chance to fire Manchester City into the fourth round after Georgios Samaras tried and failed in the first leg, while Stephen Jordan returns in place of Nedum Onuoha. Everton target Madjid Bougherra is left out for Sheffield Wednesday but Joey Barton, also a target for Everton, lines up for City.
1845: The first result of the evening is in already... Luton's Kenilworth Road pitch is deemed unplayable and their replay against QPR is called off. No news on a new date as yet.
