What happened: Former running back Chris Johnson is urging a revival of the ALS Ice Bucket Challenge to raise awareness of the progressive nervous-system disease as he battles it himself. He is asking fans and fellow players to take up the challenge again, framing it as a push for research and support rather than a viral trend.

Why it matters: The renewed call comes days after Johnson revealed his ALS diagnosis, turning a personal health battle into a broader awareness campaign. A revived challenge would reconnect the football community with a cause that first gained mass attention a decade ago, keeping funding and public attention on a disease that still has no cure.

What to watch: Watch whether current and former players answer Johnson's call and whether the campaign gains organized backing from ALS research groups in the weeks ahead.
