Mark Hughes' men led twice at Loftus Road but not even a saved penalty could stop the Royals from reaching the last 16, while Alexander Tettey's goal was enough for the Canaries
3rd Round Results
Chris Hughton's Norwich City side edged their way past a spritied Doncaster on what was an emotional night at Carrow Road, as the club paid tribute to their longest-ever-serving manager, John Bond, who recently passed at the age of 79.
The Canaries took the lead 26 minutes into the contest with a spectacular strike from Alexander Tettey, the Norwegian midfielder rifling home from 20 yards after being played in by striker Grant Holt.
Hughton's men came close to adding to that lead just seven minutes later when Jacob Butterfield saw his long-range effort well saved by Rovers keeper Gary Woods. The Premier League side continued up until the interval and the visitors were fortunate not to be further behind when Jamie McComble cleared Elliot Ward's header off the line.
The hosts were dealt a major blow early in the second half, however, as Tottenham loanee Harry Kane was stretchered off just three minutes after the break.
Norwich continued to dominate proceedings despite the sporadic nature of the second half and should have killed off the game late on as both Holt and Simeon Jackson went close to securing the win in the dying stages.
It mattered not, however, as with Dean Saunders' Rovers offering little as an attacking threat - the hosts were able to comfortably hold on and book their place in the next round.
Reading made sure of their place in the fourth-round draw with a slender win over Premier League rivals QPR in an enthralling encounter at Loftus Road.
The home side took the lead 16 minutes in thanks to a superb individual effort from Junior Hoilett, the former Blackburn man taking on several Royals defenders before slotting past Alex McCarthy.
However it was a lead that lasted little more than a minute as the visitors levelled through Kaspars Gorkss, the Latvian defender - a former QPR player - heading home a neat free kick to restore parity.
The two sides remained level until the half-time interval but that proved to be little more than a prelude to a manic second period.
Djbril Cisse restored the Rs' lead 19 minutes from time as he powered a rocket past McCarthy but their advantage again proved to be a brief one as Nicky Shorey soon drew Brian McDermott's Reading level with a superb left-footed free kick.
The tie appeared to be heading for extra time but, nine minutes from the end, the visitors edged their way ahead for the first time as Pavel Pogrebnyak showcased great awareness to send a clever backheel past Julio Cesar.
That was not the end of the drama, though, as, two minutes into stoppage time, Pogrebnyak earned a late penalty before seeing his spot-kick brilliantly saved by Cesar.
Still, that miss proved to be little more than a footnote as McDermott's men held on to secure their passage through to the last 16.
