Clay Matthews got knocked out of the game on a vicious blindside block

The Philadelphia Eagles and Green Bay Packers are looking like they'll be involved in a shootout, but the Packers will have to try and play some defense without the help of Clay Matthews. He took a nasty hit on this blindside block from Eagles lineman Allen Barbre.

And the hit was so vicious it sent Matthews back to the locker room to get checked on.
