If you don't consider the chin to be a part of the head, you're right.
Davis and Kap were spending more time running routes after practices to get on the same page. They started to click and Davis was going to be a bigger part of the O in the Fawks game..until he got his bell rung.

There's a chance Davis won't play in the Cards game either, so Walker will be called on to block more. Celek came into the game after Davis went out and had a couple of good catches.

With Manningham out it's next man up so it's about time to see whether #1 pick A.J.Jenkins can step up. His knock has been he doesn't have the upper body strength to separate from DBs at the line. He has good hands and decent speed though. The Niners have Chad Hall and Ricardo Lockette on the practice squad and they could even work out some veterans this week.

After watching that hit over and over again, I've come to the conclusion that it was a shoulder hit directly on the football. As the football became decompressed, the force pushed VD rearwards with enough additional force that his helmet came forward into Chancler's.

Ruling........clean hit, Dooooood!!

Sorry Hank I think in your age your vision is going. There is space between Davis' chin and Chancillor during that entire video.

After Seahawks safety Kam Chancellor was penalized 15 yards for the hit that knocked 49ers tight end Vernon Davis out of last week's game with a concussion, replays appeared to show the collision wasn't actually helmet-to-helmet on a defenseless receiver. Instead, it seemed like it was a clean play with a shoulder-to-chest hit.

So, a report from PFT saying Chancellor was not fined by the NFL this week for the hit seems completely reasonable.

In the end, the penalty didn't matter to the Seahawks, who blocked a 49ers field goal at the end of that drive and ended up with a 42-13 win.

Meanwhile, Davis is questionable to play this weekend vs. the Cardinals.
