Unnecessary Toughness penalty?

[Dennis in NC]

Busy week, I finally got to watch the Indy game tonight.

 

In the 2nd Q, Wire pushes a WR before the ball arrives. A penalty is called, but it's Pass Int on #57 (not sure if Stamer was on the field at the time).

 

Anyhoo, the Indy announcers show the Wire replay, say it was an Unnecessary Toughness infraction. (slip of the tongue)

 

I was amused, wondered if anyone else heard it.
