Thankfully this one was covered in the rules...
The Rules
...
Should you forget to make your selection in any week, select a team you’ve already chosen before, make a late submission or your teams fixture is postponed, you will automatically be assigned the first Premier League team that you have not already selected in alphabetical order.
So Kavah will be allocated Arsenal...who won...and proceed to the next round.
So it’s as you were. Both through to next week.
To be sure, to be sure...We will just wait and make sure the game isn’t quickly rearranged for tomorrow night...
