Just to give you a little information that is not found on the video, after the play was over and the penalty enforced, the down was replayed from the 30 yard line. The penalty called was an IBIB, so it should have occurred around the 40.
The block by the slot receiver on the left side around the 30 yard line looks suspect, but that's the only one that I can find.
Let me know your thoughts.
