A look at the relegation permutations in the Championship

Rotherham's goalless draw at mid-table Luton takes their survival hopes out of their hands ahead of the final round of Sky Bet Championship matches.

Victory on Tuesday night would have lifted the Millers out of the drop zone, above Derby on goal difference, but the draw leaves them battling alongside Sheffield Wednesday, with Wycombe needing a minor miracle to stay up.

Here, the PA news agency runs the rule over the four teams at risk of dropping down from English football's second tier.

Position: 21st

Points: 43

Goal difference: -22

Final fixture: Sheff Wed (home)

What do they need to do to survive? Victory would guarantee safety while a draw would be enough if Rotherham do not win at Cardiff, but defeat would send the Rams down as the Owls have a superior goal difference.
