Hope this link works but here is the info I am going off of although its dated 2015. Appears that an email from albertarelm will get sent out with the information about the replacement tag. I'm assuming at that point you will be able to assign a tag number to the licence and proceed as if it was a normal draw tag.
When I talked to the biologist regarding my deer she asked me if I intended to consume the meat and since my wife was 8 months pregnant at the time, We decided it was ultimately not worth the risk to take the chance to eat the meat even though most people don't feel CWD affects humans. Couldn't live with that decision if it affected my new daughter. I asked the biologist what steps I needed to take and was told to dispose of the meat which we did.
I was not required to submit anymore of the deer other then the skull for sampling, I did not have to forfeit the antlers.
