1. Combine first 9 ingredients in a small bowl. Place bison on a dish; drizzle with juice. Rub spice mixture over bison. Cover and refrigerate 1 hour.
2. Preheat oven to 425°.
3. Let bison stand at room temperature 15 minutes. Secure bison at 2-inch intervals with twine.
4. Place bison in a small roasting pan coated with cooking spray. Bake at 425° for 25 minutes or until a thermometer registers 115° or until desired degree of doneness (temperature will continue to rise as roast stands). Remove from oven; let stand 20 minutes before slicing.
