To withdraw/cancel an entry:
Open the NHL Pick’em contest.
Go to My Entries.
Find the entry you would like to remove.
Select the three dots (⋮) next to the entry name.
Select Withdraw.
Confirm that you would like to withdraw the entry.
Once the contest is in progress, the Withdraw option is no longer available and entries are locked.
Then, you will need to reach out to the commissioner of the contest, and they will need to manually remove/boot your entry from the contest.
