1Heat coals or gas grill for direct heat. In 8-inch skillet, melt butter over medium heat. Cook celery and onion in butter, stirring frequently, until celery is crisp-tender. Stir in rice, almonds, salt and pepper until well blended.
2Cut a deep pocket horizontally in each pork chop on the meatiest side of the bone. Press about 1/3 cup stuffing into each pocket. Secure openings with toothpicks. In small bowl, mix apricot preserves, wine and cinnamon.
3Cover and grill pork over medium-low heat 40 to 45 minutes, brushing occasionally with preserves mixture and turning 2 or 3 times, until pork is tender and slightly pink when cut near bone on the unstuffed sides of chops. Remove toothpicks. Discard any remaining preserves mixture.
