Update 9:10 PM: Cassel out 2-4 weeks. Head here for more.
It's the preseason. The Chiefs offensive line has been a work-in-progress for some time. Damion McIntosh had been working with the second team for a couple of weeks.
In the video above, you can see there was a breakdown at nearly every spot on the offensive line in the play that resulted in Cassel's knee injury.
Mike Goff pulled, which resulted in center Rudy Niswanger and Damion McIntosh having to double team #92 Brandon Mebane. The 6'1", 303 pound defensive tackle got a heck of a jump on the snap and was in the backfield before McIntosh could slide over to assist in the double team.
From that point, it was over for Cassel.
