Direct from Nissan Stadium: "From time to time, ticketing conflicts may arise. Should a patron's seat be occupied by another guest and the conflict cannot be resolved, contact the nearest usher for assistance or visit the fan accommodations booths on the Main Level (Sections 101 and 123) and in the Upper Deck (Sections 310 and 337). Do not sit in any open seat since this will only delay resolution. The Titans prefer to resolve ticket issues prior to game time, when possible."
