Ryan was penalized 15 yards for unsportsmanlike conduct after walking on the field and jawing with Cincinnati Bengals offensive tackle Andre Smith.

The expletives appeared to be flowing freely for Ryan, but that's the norm. He probably got the penalty because he went so far on to the field to make his point.

The Cowboys' defense had Ryan's back: They held the Bengals to a field goal despite the penalty.
