The Ghana-born Norway midfielder, signed from Rennes, marked his debut with a fine 22-yard effort midway through the first half, which proved enough to see off Dean Saunders’ npower League One side.

Although there was a start for captain Grant Holt, who has yet to score this season, Canaries boss Chris Hughton made the expected sweeping changes, with recent signings Jacob Butterfield and goalkeeper Mark Bunn all coming in.

On-loan Tottenham striker Harry Kane also started, but was carried off in the second half with what looked like a serious ankle injury.

Norwich, who have yet to win in the Barclays Premier League under Hughton, started brightly.

Tettey showed his intent early on when he let fly from 25 yards, but his shot was just over.

Doncaster had a chance on 12 minutes after a quick break down the right when Martin Woods’ shot was blocked and Robbie Blake stabbed the rebound goalward, Bunn tipping it behind at full stretch.

Goals have proved a problem so far for the Canaries, and the hosts were out of luck again as first Kane saw his effort blocked after a punch from Doncaster goalkeeper Gary Woods dropped to him in the six-yard box, before full-back Marc Tierney had a 20-yard strike tipped over.

Rovers soaked up plenty of pressure, but were dangerous on the break and midfielder David Cotterill flashed a low shot across goal.

Holt, leading scorer over the past two seasons, cut inside from the right and fired a low shot into the side netting.

Norwich finally took the lead on 26 minutes, when Tettey found his range, lashing a fine curling effort from 22 yards in off the far post.

And the Canaries continued to press.

Butterfield, also making his first start after recovering from a knee injury following a summer move from Barnsley, tried his luck from the edge of the box, but Woods got down to make a smart save.

Doncaster, though, were unfortunate not to level following a goalmouth scramble 10 minutes before half-time, Shelton Martis seeing his goalbound effort blocked in the melee.

At the other end, Rovers skipper Jamie McCombe somehow blocked Elliott Ward’s bullet header from point-blank range in first-half stoppage time.

Norwich were forced into a change on 50 minutes after Kane fell awkwardly on his ankle, and had to be taken from the pitch on a stretcher.

Woods made a smart double save to parry Holt’s low effort from 20 yards and then beat away the follow-up effort from substitute Simeon Jackson.

Holt, who spearheaded the Canaries rise from League One under Paul Lambert, went close again with a diving header at the far post on 72 minutes, before then combining with Jackson as the Canada frontman skipped around the keeper but could only slide the ball back into the side-netting.

Doncaster almost snatched an equaliser with two minutes left after full-back James Husband darted down the left and his low centre was stabbed goalward by substitute David Syers, when better contact would have seen the ball in the net rather than the grateful hands of Bunn.

Norwich, though, did enough to secure safe passage into round four for the first time since the 1995/96 season, as they paid a fitting tribute to Bond, who guided the club to Wembley in this competition almost 40 years ago.
