The big defender put in an assured display up against a lively City attack in his first game since the pre-season friendly at Celtic.
While Richards enjoyed his first outing in six weeks, Dean Marney was the driving force from midfield and Lee Barnard again caught the eye up front.
Barnard made it two goals in seven days for the reserves after his strike against Palace last week and then handed Eddie Silva Sousa his first Spurs goal on a plate in the second half.
Marney's surges from midfield were a highlight all night and having had two good chances himself - blasting the best into the stand - set up Barnard's opener on 35 minutes.
The midfielder broke a couple of tackles before unloading from 25 yards, the ball cannoned back to him and this time he fed Barnard who stroked the ball home with some aplomb.
The Canaries had threatened a couple of times before that goal and should have levelled before the break.
Paul O'Donoghue tripped Ryan Jarvis right in front of goal for a cast-iron penalty. Jarvis stepped up himself, Marton Fulop saved superbly low to his right only for the linesman to flag for an infringement - possible Fulop straying off his line before the ball was kicked - and the referee ordered a retake. Jarvis grabbed the ball again and this time blasted into the Row Z.
That miss proved costly as we capitalised on our best football at the start of the second half with a fine second goal on the hour.
The impressive Jamie O'Hara released Marcel McKie down the left, he reached the byline and cut back for Barnard who dummied and allowed Silva Sousa to finished well from 10 yards.
Barring another Marney surge and rocket that Ward couldn't hold, Norwich actually carved out the better chances in the last half-hour. However, Crow couldn't take advantage and when Fulop was beaten, Stephen Kelly was there in injury time to block a certain goal.
