Texans' Joe Mixon presses NFL after no-call on alleged hip-drop tackle that caused injury

The NFL banned swivel hip-drop tackles earlier this year and vowed to penalize anyone who decided to use the technique during play.

The tackling technique has been the catalyst for some injuries around the league in recent years. The NFL commissioner led the way for the rule to be voted on, which received unanimous approval from owners despite pushback from the NFL Players Association (NFLPA). The union said it could not support a rule that would cause confusion for players, coaches, officials and fans.
