Chiefs HC Andy Reid questions NFL rule regarding Chargers DT's slap of Travis Kelce

Tart was allowed to stay on the field because of a technicality in the league's rulebook. Defenders are not allowed to strike an opponent's head with a closed fist. However, there is an exception, as "contact to the head, neck, or face of an opponent with the palm of the hand is permitted."

The Kansas City Chiefs are confused about an NFL rule

Tart landed his blow with the palm of his hand, which was the reason the defensive tackle was not ejected. Still, the rulebook allows for officials to penalize a team 15 yards and eject the player if the "entire action" is determined to be "flagrant."

Based on the replay, Tart appeared to use a flagrant action against Kelce, but the officials chose not to apply the subjective ruling against the Chargers. Los Angeles would go on to win the game, 27-21, with Tart on the field.

Per Yousuf, Reid was asked if he planned to ask for clarification from the league on the matter. He plans to work out what happened with the league, but didn't go into more detail because he didn't want a fine.

The league cracked down on taunting and unnecessary violence during much of Week 1, ejecting Philadelphia Eagles defensive tackle Jalen Carter for spitting on Dallas Cowboys quarterback Dak Prescott. For whatever reason, the league didn't want to apply that emphasis to Tart.
