The NFL plans to send out a video to all 32 teams that will specify what is considered unsportsmanlike conduct, senior vice president of officiating Dean Blandino said Tuesday,

Taunting calls are up 220 percent in the first four games of 2016 as opposed to last season, according to ESPN.com.

Other unsportsmanlike penalties, such as celebration dances, are up 56 percent.

"We certainly want the teams to have clarification," Blandino said on NFL Total Access, "and this isn't a new issue. We've been dealing with this in the past. And so we're going to send a tape out in the next week or so and clarify some of these things. But the key is if it's a gesture that either mimics a violent act — that's something with a firearm or a bow and arrow — or a sexually suggestive act, those are unsportsmanlike conduct.

"That's ... something that officials will flag. That's direct from the competition committee and something that we're going to try to be as consistent as possible."

A prime example is Pittsburgh Steelers wide receiver Antonio Brown, who was penalized in Week 1 for twerking in the end zone. He vowed to limit his celebration to "two pumps," but was hit with another penalty last week for making a thrusting motion after catching a touchdown.

Steelers coach Mike Tomlin said Tuesday he and his players didn't know what was considered unsportsmanlike and what the league considers to be acceptable.

"We have to get some clarity in terms of what's legal and what's not," Tomlin said.

Another example is Redskins cornerback Josh Norman, who was hit with a penalty on Sunday for his bow-and-arrow motion after he was penalized in Week 2 for the same celebration.
