"I think it was just landing on him with the tackle. I don't know," Kpassagnon said, via Arthur Arkush of Pro Football Weekly. "I guess they kind of want me to do something that a lot of people think is physically impossible."
In an effort to make the game safer, the NFL implemented a new helmet rule back in March. The new rule states that it is a foul if "a player lowers his head to initiate and make contact with his helmet against an opponent." A violation of the rule can result in a 15-yard penalty, a possible disqualification and a possible fine.
This preseason is being used to test out the new rule during games, and the league will evaluate each call afterward. However, there has been no shortage of controversy surrounding the new rule. ESPN.com's Chris Mortensen reported the NFL will issue an updated teaching video at the end of the preseason to try to provide clarity.
In the meantime, though, players around the league have come on strong in ripping the new rule.
Kpassagnon's teammate, fellow Chiefs linebacker Justin Houston, sounded off after Saturday's game, via Brooke Pryor of the Kansas City Star:

LB Justin Houston had some strong words after the roughing the passer penalty on Tanoh Kpassagnon “I understand they want to keep us safe but this is a contact sport. You try to take out the contact in it. We know what we signed up for. It’s not like no one’s making us do this” https://t.co/kUW73kWaKr
Meanwhile, San Francisco 49ers cornerback Richard Sherman called the rule "idiotic":
But they aren't alone in their criticism:
The league was hoping to make football safer by forcing the players to change the way they tackle, and so far, it has led mainly to controversy.
