It took a lot longer for the 2010 Red River Rivalry tickets to sell out Tuesday compared to previous years.

Ticket sales began at 7 a.m. Tuesday, and the supply of 4,700 tickets lasted for almost nine hours, selling out around 4 p.m.

In contrast, last year’s 4,200 tickets sold out in 30 minutes. It took only two-and-a-half hours to sell 2008’s 4,000 tickets.

Tickets were $110 this year.

This season’s Red River Rivalry is at 2:30 p.m. Oct. 2 at the Cotton Bowl in Dallas.
