Willis defends his hit on Hasselbeck as clean

SAN FRANCISCO -- Patrick Willis defended his hit on Matt Hasselbeck as clean and within the rules.

"I just know it wasn't an illegal hit," Willis said. "I didn't take my helmet and spear him right in his back. It was shoulder pads. I knew he was hurting a little bit as well, but I don't know what is the deal. I hope he is OK."

I pass that along because some have suggested in the comments that Willis took a cheap shot at Hasselbeck. I need to see a better replay to know for sure.
