What happened: Aljamain Sterling dismissed the proposal as "bullshit" and questioned the focus on recovery time. He contrasted oblique kicks with bare-shin head kicks and raised CTE as the larger danger.

Why it matters: The exchange centers on which techniques regulators should restrict in the name of fighter safety. Sterling's response frames oblique kicks as a lesser concern than head trauma under current rules.

What to watch: Whether Foster answers and if any commission takes up the proposal will show if the idea advances.
