The video is of Nate Chandler getting his poo rocked by Marcell Dareus. I remember seeing that live and hoping that it was a reserve.
I've watched that video a few times and rewatched that play live on dvr. #99 flashed to the RG spot where turner had just gone up field to block the LB. With the size differential and the fact that the movement was crunched towards the C there was next to nothing Chandler could have done to stop that lineman. The fact that he got thrown to the ground makes it look horrible, which it was, but it was a blown blocking scheme or turner missed his assignment, IMHO.
