Irate during an animated discussion Sunday with referee Terry McAulay, Texans coach Bill O’Brien threw his headset.

One day later, O’Brien with a deadpan expression said, “I dropped it” when asked what happened and declined to elaborate on what set him off during the Texans’ 30-6 win over the Jacksonville Jaguars.

How did O’Brien get out of an unsportsmanlike conduct penalty?

“Two Irish guys,” O’Brien said with a smile. “He forgave me.”
