Norwich, QPR, Swansea and Sunderland crash out in round two
MK Dons, Rochdale, Shrewsbury and Brighton claimed Premier League scalps on Tuesday, with Queens Park Rangers, Norwich, Swansea and Sunderland crashing of the Carling Cup at the second round stage.
Elsewhere, Aston Villa, West Brom, Wolves, Leicester, Leeds, Nottingham Forest, Burnley, Cardiff and Millwall all marched on, avoiding any potential banana skins.
Norwich have made a steady start to life in the top flight but, having made 11 changes, they came unstuck against
MK Dons, with Carrow Road old boy Luke Chadwick bagging a brace in a 4-0 win for the current leaders of League One.
Queens Park Rangers were also felled on home soil, with an early effort from Jean-Louis Akpa Akpro and a late strike from Gary Jones enough to see
Rochdale into round three.
Swansea ensured that all three of the Premier League new boys bowed out on Tuesday, with Marvin Morgan, Mark Wright and Nicky Wroe on target in a memorable 3-1 victory for
Shrewsbury.
Upset
Sunderland became the fourth top flight side to fall as Craig Mackail-Smith struck in extra-time to send
Brighton into round three.
There was no such mishap for
West Brom, as Roy Hodgson's men eased past
Bournemouth 4-1 at Dean Court.
The Baggies' Black Country rivals
Wolves are also in the hat following a 4-0 victory over
Northampton.
Alex McLeish took Birmingham all the way last season and he is a step closer to defending that crown after seeing Eric Lichaj and Nathan Delfouneso secure a dramatic 2-0 win for
Aston Villa over plucky
Hereford.
Leicester survived a scare at
Bury, having trailed at one stage, but eventually prevailed 4-2 in a thriller at Gigg Lane.
Comfortable
Nottingham Forest saw Ishmael Miller net his first goal for the club in a comfortable 4-1 win away at
Wycombe.
Millwall made light work of
Morecambe, who have made a bright start to the League Two campaign, with Hameur Bouazza and Tamika Mkandawire helping them to a 2-0 success.
Ramon Nunez has been among the goals for
Leeds in the league of late and he was able to transfer that form into knockout competition as his double helped the Whites down
Doncaster.
Cardiff were involved in an eight-goal thriller with
Huddersfield, with Craig Conway and Don Cowie eventually settling a topsy-turvy encounter in extra-time.
Jay Rodriguez put four past Burton Albion in round one and he was on target again in round two as
Burnley struggled to a 3-2 victory over League Two side
Barnet, with Chris McCann wrapping things up in the 105th minute.
