Stir sage, salt, parsley, red pepper, fennel, black pepper, smoked paprika, coriander, and thyme together in a small bowl.
Place ground pork in a bowl, add seasoning mix, and mix well using your hands until all ingredients are evenly distributed. Form into a roll about 2 inches in diameter and 6 inches long. Wrap tightly in plastic wrap and refrigerate for 8 hours, or up to 24 hours.
Clean and preheat an outdoor grill for medium-high heat and lightly oil the grate.
Slice seasoned pork into twelve 1/2-inch thick patties.
Place patties onto the hot grate. Close lid and allow to cook for 1 1/2 minutes. Rotate each patty 90 degrees and continue grilling for 1 1/2 minutes at a time, until juices run clear, 6 minutes total. An instant-read thermometer inserted into the center should read at least 145 degrees F (63 degrees C).
