Two goals from Irish striker Shane Long consigned Norwich to a 2-0 defeat at home to promotion-chasing Reading and did the Reds a massive favour in their fight to avoid relegation.
Tonight's result means that the Reds only need a point away at now safe Plymouth to ensure they will be playing Championship football next season.
However, the permutations also state that if the Reds lose at Plymouth and Norwich win at Charlton then Barnsley will be relegated.
It's sure gonna be a nervous Sunday!!
