Note:

If normal time draw, no extra time, straight to penalties, 5 each then sudden death. This includes group games to help break points ties on head to head result. Normal time wins have tie break advantage over penalty wins.

Teams who default in cup competition fixtures may forfeit their participation in fall-back competitions linked to the cup competition in which they defaulted. In seeded knock-out competitions where the losing teams fall-back into a lower level competition, an unseeded team who wins a fixture due to a seeded team defaulting may still fall-back into the lower level competition if they prefer and the League agrees, allowing the seeded team to progress in the higher level competition
