Not all tickets for sports events or shows are nominative. Therefore, in some cases, the name of the person who made the purchase may appear.
Additionally, for certain sports events, tickets may come from season ticket holders who cannot attend and put their seats up for sale, so the name of the season ticket holder may appear.
This is a completely common situation and does not affect access to the event at all, so you can enjoy the experience with complete peace of mind. Only when it is necessary to identify the attendee will the tickets include your name.
