REPORT: CITY 1-0 SOUTHAMPTONALEX Tettey's strike secured Norwich City their second consecutive Premier League win as they beat Southampton 1-0 at Carrow Road.
Tettey guided the ball into the top corner moments after Victor Wanyama had been sent off for the visitors following a second bookable offence.
City ceded possession to their opponents for large periods of the game, but in terms of chances created there was little between the two teams.
That made the final result even sweeter for Alex Neil's men, who have now won three of their last four matches in the top flight to put some breathing space between them and the bottom three.
City made just one change from Monday's win over Aston Villa as Gary O'Neil returned in place of Graham Dorrans.
Jonny Howson played in a central role off Dieumerci Mbokani, with Wes Hoolahan on the left flank. Youssouf Mulumbu returned to the substitutes' bench, with Kyle Lafferty dropping out of the matchday squad.
Former Norwich loanee Ryan Bertrand started at left-back for Southampton, who entered the game having won just one of their last seven league matches.
The Canaries carved the first opening of the game on 11 minutes when Mbokani's strength in the air allowed Howson the opportunity to beat Jose Fonte to possession, but he couldn't get over the bouncing ball and poked his shot wide.
Southampton then forced a save from Declan Rudd when Dusan Tadic and Bertrand combined to set up Ward-Prowse on the edge of the box, but his effort was straight at City's goalkeeper.
There was a little in the contest, with the visitors edging the possession stats but it was City who could have netted after the half hour mark when Mbokani nudged wide from close range after Russell Martin's square ball.
Straight up the other end, Ronald Koeman's side went close to breaking the deadlock when Shane Long got beyond City's last line of defence, but Rudd was fast off his line to make a vital block.
Virgil Van Dijk then stooped low to head a James Ward-Prowse corner wide as Southampton continued to carry the greater threat, but only by a small margin in a competitive game.
One minute before the break, Mbokani went close to giving his team a half-time advantage, but he turned Howson's cross narrowly over Maarten Stekelenburg's bar.
HALF-TIME: Norwich City 0-0 Southampton
There was a tense feel to the opening part of the second half as both teams endeavoured to find that crucial opening goal.
Soon after Tettey scooped a shot over the bar from 20 yards, Alex Neil made his first change as Vadis Odjidja stepped on for Redmond.
Russell Martin guided a difficult header wide from Howson's cross before, for the visitors, Tadic raced onto a Stekelenburg long pass only to lift his shot over Rudd's bar.
City's cause for a winner was boosted on 74 minutes when Wanyama was dismissed after picking up a second yellow card, and two minutes later the Canaries took full advantage.
Substitute Odjidja was having an impact and it was him who set up Tettey to guide a superb finish into the top corner from the edge of the box.
Southampton, despite their man disadvantage, dominated the game after going behind, but City held on for another cleansheet - a three more precious Premier League points.
