What spooky uniform and jerseys combinations are Pac-12 football teams wearing this Halloween? The field includes scary blackouts, ghostly whiteouts and Oregon State wearing fitting but standard attire. Nonetheless, the highlight of the week is Arizona State's honor of Pat Tillman, who lost his life in the line of duty.

The Huskies are prepared for Halloween. They'll don black on black on black while hosting Arizona.

Take a look at how the Huskies will suit up for tomorrow's blackout game. Be there: https://t.co/eccae5bljR pic.twitter.com/kpdMAoda6k

A painful triple-overtime loss Thursday against Oregon served Arizona State an opportunity to honor former Sun Devil Pat Tillman with quite the unique tweak. Every player had a Tillman nameplate on the back of their jerseys as part of a combination put together by both adidas and the Tillman Foundation.
