Looked to me like Suh got up by trying to move through the area occupied by Morris' head. Most players get up by moving into open space. I doubt this was unintentional, but how can you prove it? You can't, and that is why he does it. No different than the "accidental" step backwards last year, right onto Aaron Rodgers leg. It was an awkward, long step; but you can't prove any intent. Just a coincidence that he landed on such a small target, and a gimpy one at that.
