Northwestern's defensive shakeup

It’s all about changes.

Before Northwestern kicked off against Penn State Saturday

night at Ryan Field, a few defensive changes were announced.

Injuries to defensive lineman Tyler Scott (neck stinger)

and Bryce McNaul (back spasms) have the Wildcats looking to Kevin Watt at

defensive end and Chi Chi Ariguzo at outside linebacker.

But in the shaking things up department: Quentin Williams

is starting in place of Vince Browne at one defensive end, Damien Proby at

middle linebacker in lieu of David Nwabuisi and David Arnold at safety instead

of redshirt freshman Ibraheim Campbell.
