Northampton and Cheltenham both lost in tonight's League One matches.
The Cobblers lost to Saturday's opponents MK Dons 1-0, while the Robins were beaten 3-0 at Scunthorpe. The Iron face Tranmere on Saturday needing to draw to claim the final play-off spot. Should they lose it will be Tranmere that take the final spot.
For the Cobblers the loss means they will still require a point on Saturday to ensure safety. Their far superior goal difference should see them safe with a draw, while Brighton will likely need three points to survive the drop if Carlisle win their final match. Crewe will require both the Seagulls and Cumbrians to lose and make up four goals to escape the drop.
