Northampton, Mansfield, & Huddersfield have already been relegated from Division 2, and either Cheltenham or Chesterfield will join them.
If Chesterfield win at the weekend Cheltenham will go down, but if Chesterfield draw, and Cheltenham win then Cheltenham will stay up. If Chesterfield lose and Cheltenham draw then Cheltenham will also stay up, and if both sides lose then Chesterfield will stay up.
