BBAO: Scott Kooistra played with C-2 injury

We're Black and Blue All Over:

We all know most NFL players stay on the field when they suffer mild injuries. But over the weekend, two from the NFC North pushed through in quite unbelievable fashion before getting a serious postgame diagnosis.

We've already discussed Green Bay Packers linebacker Frank Zombo, who fractured a shoulder blade during pregame warm-ups but still saw significant action in the Packers' preseason game against the Arizona Cardinals. Zombo could miss the season.

Now, as Tom Pelissero of 1500ESPN.com reports, we know that Minnesota Vikings guard Scott Kooistra suffered an injury to the C-2 vertebrae near the top of his spinal cord after starting against the Seattle Seahawks. As of Monday night, he was hospitalized in stable condition in the Seattle area. The Vikings, who might have called upon Kooistra as their starting right guard while Anthony Herrera rehabilitates his knee, have already placed him on injured reserve.

And you think preseason football doesn't mean anything to anyone? Wow.
