The NFL has come down hard on taunting this season, and on Sunday Detroit Lions offensive lineman Jonah Jackson was given a costly unsportsmanlike conduct after insulting Cleveland Browns defender Jadeveon Clowney’s mother. 

Lions coach Dan Campbell told reporters after the game that both sides were going at it late in the third quarter when "something about somebody’s mother" was said.

"I don’t know what to tell you," he said, via the Detroit Free Press. "It was something that is said. It was something about somebody’s mother, OK? And there was a lot of talking going on out there, but so it was a penalty."

D'Andre Swift rushed for 13 yards for a first down, but after Jackson was flagged for unsportsmanlike conduct, Detroit opened the fourth quarter first-and-25 from their own 43 and was unable to convert for a first down, trailing 13-7.

"First of all I should have never even put my team in that situation, but it was the heat of the moment, heat of the game," Jackson said of the insult. "We actually chopped it up after, apologized. It was both sides, but definitely should have never been in that situation to begin with."

The Browns held on to avoid an upset and keep the Lions winless with a sloppy 13-10 victory as the NFL added another taunting no-no to its already long list of unacceptable behavior.
