You cannot sell tickets to Dallas Cowboys playoff games until the games are clinched. Shortly after the teams are decided for each game, you can sell your playoff ticket(s) from the Dallas Cowboys Account Manager. Click here to learn how to sell tickets on the SeatGeek Marketplace.
Provided that the game you sold tickets for has already been clinched, your payout will be issued 24 hours after the sale. Once issued, a payout will take 3-5 business days to appear in your bank account.
