As of 3:45 PM EST, there were approximately 250 total seats still available in the four sections behind the Hillsdale sideline.
Currently, Section 10 is sold out. Sections 11 and 12 are nearly gone, while close to 200 remain in section 13. There is standing room to the sides and behind those sections. Reserved seats may sell out, but any Charger fan wanting to be on that side can still be accomodated.
Call 616 331-3200. Hours are between 9 AM and 6:00 PM. I received a recording several times before finally getting through to a salesperson. Keep redialing.
