Port Vale win 3-2 on penalties
Port Vale beat Norwich City 3-2 on penalties to reach the fourth round of the Carling Cup for the first time in their history.
Jeff Smith scored the decisive spot-kick after both sides had failed to find the net in open play.
It was Vale who had the best chances and Dan Whitaker went closest for the home side when he hit the crossbar in the closing stages of extra time.
Norwich boss Peter Grant chose a strong side but suffered his first defeat.
Vale, who are in mid-table of League One, had already disposed of two other Championship sides in Preston and QPR to reach this stage and the Canaries were to become their third victims.
Leon Constantine had two early chances for the home side, with Norwich keeper Paul Gallacher saving well from his header.
Gallacher saved well again from Micahel Husbands after the break while two Dixon Etuhu shots were the best openings City could muster.
Dion Dublin wasted a glorious chance for the visitors when he headed wide from six yards but otherwise Grant's side struggled to open up Vale.
When it came to penalties, Vale's Paul Harsley and Norwich's Peter Thorne were the only scorers after three spot-kicks each.
After Robert Eagle hit the bar for City, Whitaker made it 2-1 to Vale - and although Dublin kept Norwich in it, Smith slotted home the winning penalty.
