Norwich has progressed to the next round, after edging past QPR in the first round of the Carabao Cup tie, with penalties drawing near.
The Canaries had made eight changes after Saturday’s 4-4 league draw at Southampton, while the hosts handed starts to seven players who were on the bench in Saturday’s 2-1 victory at Cardiff.
Norwich started the better side as Kenny McLean sent a top volley over the bar and 32nd-minute substitute Onel Hernandez volleyed a Przemyslaw Placheta cross straight at Jordan Archer.
Teenage Norwich full-back Kellen Fisher fizzed over the bar of Joe Walsh – who substituted Archer in the Hoops goal at half-time – before Hernandez was forced off after a heavy fall.
With a 99th-minute header, Jonathan Rowe’s stoppage-time header booked Norwich a second-round trip to face Bristol City at Ashton Gate on 29 August.
The crowd erupted with joy as nobody wanted penalties.
