[QUESTION] Dry rub recipe ingredient

Hello everyone I am currently making an American Dry Rub by The BBQ Pit Boys the recipe is as follows

• 1/2 cup Brown Sugar
• 1/4 cup Paprika
• 4 tablespoons Coarse Salt
• 3 tablespoons Coarse Pepper
• 2 teaspoons Onion Powder
• 2 teaspoons Garlic Powder
• 2 teaspoons Celery Seed
• 1 teaspoon Cayenne Pepper

My question is can I proceed to make this without celery seeds/leaves? Will it have a large impact on my rub or not and I thank all answers in advance!
