Norwich City edged past Championship rivals Queens Park Rangers with a 99th-minute goal in a low-key EFL Cup first-round meeting.
With penalties looming, substitute Jonathan Rowe headed in with the last action at Loftus Road in a game which only sprung to life in the closing stages.
The Canaries had made eight changes after Saturday's epic 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.
Rowe's third goal in as many games - and second stoppage-time winner - booked Norwich a second-round trip to face Bristol City at Ashton Gate on 29 August.
