Former Tennessee Titans and Arizona Cardinals running back Chris Johnson is looking to rally the public to bring back a familiar movement to help fight amyotrophic lateral sclerosis.

The 40-year-old former running back, who shared earlier this week on "Good Morning America" that he is living with ALS, posted a call to action on Instagram to revive the Ice Bucket Challenge. The viral campaign first swept across social media during the summer of 2014, raising awareness and significant funding for research into the progressive nervous system disease.

Johnson noted that a video from former Utah men's basketball player Hunter Mecum, who dumped ice water over his head to honor the former NFL star, inspired him to make the request.

In his social media post, Johnson expressed gratitude for the outpouring of encouragement he received following his announcement. He noted how the original campaign brought millions together for a single cause and expressed hope that people could recreate that momentum today.

To get things moving, Johnson tagged former All-Pro running back Marshawn Lynch alongside former Titans teammates LenDale White and Adam "Pacman" Jones, challenging them to take part. He later updated his Instagram Stories with footage of White and others participating in the challenge. Johnson also shared a clip of his daughter pouring ice water over herself before she passed the challenge along to her brothers and Los Angeles Lakers star LeBron James.

During his television interview with co-anchor Michael Strahan, Johnson revealed that his diagnosis came last year. He utilized a speech-generating device that used recordings of his own voice to communicate. Johnson explained that because there is no prior family history of the disease, doctors believe he has sporadic ALS, which accounts for the vast majority of cases. He noted how shocking the condition can be because it can impact individuals who have no reason to expect it.

The campaign Johnson wants to restore originally generated an estimated $135 million in the United States and $220 million globally, according to data from the ALS Therapy Development Institute.
