Professional rugby union will classify hip-drop tackles as dangerous play from November 1, World Rugby announced Thursday.
The ban will begin before the remaining Nations Championship Tests, following discussion at World Rugby's Shape of the Game summit in February.
World Rugby chairman Brett Robinson said: "We're grateful to unions for raising the issue of these types of tackles with us. Once we looked at the evidence, it was clear the hip-drop tackles whilst rare, could cause significant leg injuries."
He added: "Protecting player welfare is at the heart of everything that World Rugby does and once we'd reviewed the analysis we've acted quickly to ensure that dangerous tackles of this nature are removed from the game."
The decision follows high-profile injuries across several sports. Nathan Cleary broke his fibula and dislocated his ankle in the NRL preliminary final after a tackle by Newcastle hooker Phoenix Crossland.
Crossland received a four-game suspension, missing the NRL grand final, and will sit out three games for New Zealand at the Rugby League World Cup.
The NRL banned the tackle in 2020, and it was already prohibited in New Zealand junior and community rugby. At professional level, it had not previously been penalised in rugby union.
Crossland became the first NRL player sent off for the tackle. In the NFL, Kansas City Chiefs receiver Tyquan Thornton suffered a long-term ankle injury in a similar incident against Las Vegas this week.
Queensland Reds talent Treyvon Pritchard, Wallabies winger Max Jorgensen, All Blacks scrumhalf Cam Roigard and Brumbies hooker Lachlan Lonergan have also been injured by hip-drop tackles in the past two years.
Reds football boss Sam Cordingley had criticised officials' inaction, warning the technique can have "catastrophic" consequences.
