LJ - Unsportsmanlike Conduct, then Taunting?

[Jack]

I watched the game. LJ chased down the Samoan fellow, got a hand full of hair and made the stop. I recorded the game and cannot find any "taunting" gestures. LJ was up and had his back to this fellow and he jumped at LJ, who seemed to just ignore him.

Anybody see this different? I think the ref just figured grabbing hair was a violation and tossed the flag. He called unsportsmanlike conduct to cover his faux pax? Later, the announcer said "he meant tauting".

Sorry if this issue has been covered in another thread, looked but couldn't find anything.
