Match ends, Norwich City 3, West Bromwich Albion 0.
Norwich advanced to the fourth round of the League Cup with victory over Premier League rivals West Brom.
Alex Neil's side broke the deadlock in the second half when debutant Dieumerci Mbokani slid in Matt Jarvis, who rattled in a rasping drive off the bar.
Northern Irishman Kyle Lafferty, making a rare club appearance, doubled the lead with a fine low finish.
An own goal from defender Sebastien Pocognoli completed a miserable evening for West Brom.
West Brom were denied a consolation when Declan Rudd made a strong fingertip save from Rickie Lambert's shot from distance as Norwich held on for their first League Cup clean sheet since September 2012.
Canaries captain Gary O'Neil had hit the woodwork with a deflected long-range drive in the first half.
Defeat extends West Brom's poor run in the League Cup - they have only passed the third round in two of the last 10 seasons.

Norwich manager Alex Neil: "Matt Jarvis was excellent, as was the rest of the team.
"Kyle Lafferty did great. He got his goal and for the third if he wasn't in that position the ball wouldn't have gone in the net.
"There were a lot of pleasing performances all over the pitch. Everything worked really well for us."
West Brom manager Tony Pulis: "Three-nil was a bit harsh, especially in the second half.
"At 1-0 we had some very good opportunities. James McClean, he could have stepped round the goalkeeper and touched it in.
"Then they get the same situation down their end, Lafferty scores and it's the end of the game. I don't think it was a reflective score."
