West Brom 0 Rotherham 1
Last Updated: 01/01/70 1:00am
The Millers have been in superb form in 2004, and showed that they can provide major shocks with a late winner against Gary Megson's side.
Chris Sedgwick was the hero for Rotherham, latching onto a Richie Barker flick on to capitalise on shoddy defending and fire home past Russell Hoult.
West Brom had seen Rotherham's Mike Pollitt in scintillating form to deny them an opener.
The goalkeeper had kept West Brom at bay throughout, ably helped by his defence, and saved victory in the dying seconds when he turned Jason Koumas's free-kick onto the crossbar.
Norwich now hold a three point advantage, and have a game in hand as the race for the championship hots up.
