My gramma drew her OIL moose tag a few years back, she was battling lung cancer and going through chemo. We were out for 1 day of rd hunting and she got super sick and could not hunt. She talked to her doctor who wrote a note stating she was unable to hunt because of her health. it was a little bit of a process but WDFW restored all of her points. Its worth a shot for sure in my opinion. This is an unfortunate situation and i hope he makes a full recovery.
