Texans running back Joe Mixon isn't happy with the league's lack of enforcement on hip-drop tackles — and he's letting them know it. 

The 2024 NFL season was supposed to be the first year that hip-drop tackles were penalized. The tactic was part of the new rule changes agreed to by the NFL and the NFLPA. 

However, early in the campaign, it appears as though it is an ongoing issue. Mixon called out the NFL and the NFLPA after he was injured during the Texans' 19-13 win over the Bears on "Sunday Night Football."

Joe Mixon calls out NFL after injury drop hip-drop tackle

Mixon called out the league and the NFLPA on social media following the "Sunday Night Football" win after suffering an injury from an apparent hip-drop tackle. 

"The NFL and NFLPA made it a rule and an emphasis for a reason," Mixon said. "Time to put your money where your mouth is."

In a follow-up post, Mixon claimed he asked the referee why there was no flag called on the play, and the official reportedly told him the tackle was not a hip-drop one.
