Kenny McLean scored a first-half winner as Norwich beat fellow Premier League side Wolves in the FA Cup fourth round.
Scotland midfielder McLean flicked in a header into the far corner from compatriot Billy Gilmour's cross.
Norwich striker Adam Idah was twice denied by John Ruddy, while Wolves were desperately poor in the first half.
Although Daniel Podence struck a post and Ruben Neves connected with a volley in an improved second-half showing, Bruno Lages' side could not equalise.
Striker Raul Jimenez, who scored the winning goal against Panama in World Cup qualifying on Thursday, was introduced in the 64th minute but dragged a shot wide in stoppage time.
