The biggest was Newcastle United who lost 3-1 at League Two side Stevenage.
Other shocks saw Blackpool beaten 2-0 at Southampton, Norwich City beaten 1-0 at home by Leyton Orient who had Andy Whing as a 26th minute substitute, Lee Hughes score the winner for Notts County in a 2-1 at Sunderland, Burton Albion beat Middlesbrough 2-1, Brighton beat Portsmouth 3-1, Sheffield Wednesday won 3-0 at Bristol City with Clinton Morrison on target, Reading beat West Brom 1-0, whilst Leeds drew 1-1 at Arsenal, Cardiff drew at Stoke and Doncaster drew 2-2 with Wolves.
The draw for the Fourth Round is on ITV1 tomorrow at 3.45pm and Coventry City are ball number two.
