Football fans seeking tickets for today's game -- scheduled to begin at 1:35 p.m. with the San Francisco 49ers taking on the New Orleans Saints -- should look out for counterfeit tickets that authorities believe are circulating through the ticket market.
Football officials said some counterfeit tickets have already been confiscated.
To ensure fans are carrying authentic tickets authorities said to only buy tickets through reputable vendors such as the NFL Ticket Exchange managed by Ticketmaster.
Fans are urged to know their ticket source before purchasing from second-hand or non-official sources.
Officials warned that because today's game is sold out counterfeit tickets cannot be replaced.
