Beckford brace earns Leeds replay
Burnley were the day's Premier League fall guys, losing 1-0 to Championship Reading while Wigan Athletic escaped humiliation by the skin of their teeth, drawing 2-2 at League Two Notts County after trailing 2-0.
Premier League Wolverhampton Wanderers needed a late equaliser to draw 2-2 at home to Championship side Crystal Palace and Fulham had some tricky moments before winning 3-1 at the lowest-placed survivors Accrington Stanley.
League Cup finalists Aston Villa had to work hard to advance with a 3-2 defeat of third-tier Brighton & Hove Albion at Villa Park while Birmingham City stretched their unbeaten run in all competitions to 15 with an impressive 2-1 win at Everton.
