Brentford suffered a shock 4-0 home defeat against League Two Oxford as seven Sky Bet Championship sides were ousted from the Capital One Cup on a night of first-round upsets.
The visitors ran riot in the opening stages of the game at Griffin Park as Liam Sercombe, Danny Hylton and Kemar Roofe - the latter from 40 yards - put them 3-0 up inside the first 12 minutes, and Johnny Mullins' second-half effort completed the rout.
Along with Brentford, Championship rivals Bristol City and Huddersfield were also humbled by opposition from the fourth tier.
The Robins went down 3-1 at Luton, for whom Jack Marriott - with a brace - and Paul Benson got on the scoresheet before Callum Robinson's consolation.
Huddersfield threw away the lead in a 2-1 home loss to Notts County, with Liam Noble's double turning the contest around after Murray Wallace had put the hosts in front.
Four-time champions Nottingham Forest, Bolton, Blackburn and Burnley were other major casualties, all four falling to defeat against League One opposition.
Tom Bradshaw's hat-trick, including a stoppage-time winner from the penalty spot, steered Walsall to a thrilling 4-3 triumph at Forest while Bolton were undone at home by Burton courtesy of Matt Palmer's late goal.
Blackburn succumbed 2-1 at home to Shrewsbury, James Collins and Tyrone Barnett notching for the away team either side of a Liam Lawrence own goal, and Burnley lost 1-0 at Port Vale where Byron Moore's late strike settled things.
