The domestic competition is the only chance both sides have of claiming a trophy this season.
Roy Hodgson has stated that he is likely to make changes in the Baggies side with one eye on their league match against Fulham on Wednesday. It is possible that Nicky Shorey will start at right-back with Gareth McAuley and Craig Dawson holding the defence.
Billy Jones has missed West Brom's last two fixtures with a hamstring strain but could return to the starting lineup, replacing Paul Scharner who is dealing with an injury.
West Brom: WDLLLW
West Brom: Foster; Jara, McAuley, Dawson, Shorey; Morrison, Jones, Tchoyi, Dorrens; Fortune, Cox
Norwich: Ruddy; Whitbread, Ayala, Martin, Tierney; Johnson, Howson, Pilkington, Hoolahan; Morison, Holt
Sports Mole says: 1-2
