Cash turnstiles will be available on Boxing Day as the Black Cats welcome reigning Premier League Champions Manchester City to Wearside.
The Stadium of Light ticket office will be open from 10am on the day for those supporters wishing to purchase tickets and collection points will also be open from 10am.
The club is advising supporters that the ticket office and ticket collection points are expected to be busy and they should arrive in sufficient time, where possible, to avoid potential queues and delays.
Supporters are also reminded that concession tickets can only be purchased from the ticket office (proof of age required) and are not available at the turnstiles.
Turnstile numbers 13 and 14 will be open from 1:30pm for cash sales on the day.
Tickets can be purchased in-person at the Stadium of Light ticket office, online by clicking here or by calling 0871 911 1973.
