Chris Johnson is speaking publicly about a diagnosis that has changed his life, but not his identity.
The former Tennessee Titans and Arizona Cardinals running back, who owns the NFL’s single-season record for yards from scrimmage, revealed Monday that he has ALS, short for Amyotrophic Lateral Sclerosis and commonly known as Lou Gehrig’s disease. Johnson, 40, shared the news during an interview on “Good Morning America” with host and Pro Football Hall of Famer Michael Strahan.
“First, I want people to know that I’m still me,” said Johnson, who answered questions using a speech-generating device triggered by his eyes. “ALS has changed what my body can do, but it hasn’t changed who I am.”
Johnson said his journey started last year, when he noticed weakness in his right hand. At first, Brittany Johnson believed it was something tied to football rather than ALS.
“I thought, because of football and his career, that it had to be something with that,” Brittany said on “Good Morning America.” “Maybe a pinched nerve, or something along those lines, but never ALS.”
After a series of tests, doctors confirmed the diagnosis. Johnson said he has no family history of ALS, which makes his case sporadic ALS, the most common form of the disease. Doctors also told the family about a medication that could extend his life for a few months and advised them to get their affairs in order.
“It was hard hearing that,” Johnson said.
He also described how quickly the disease has moved. “It’s continued to progress much faster than I ever imagined.
I want people to understand just how quickly ALS can attack your body. Just over a year ago, I was picking up my 7-year-old daughter so she’d make a wish with her birthday cake.
Today, I couldn’t do that.”
Johnson’s playing career stretched across 10 NFL seasons, and he retired from the league in 2017. Drafted by the Titans in the first round of the 2008 NFL Draft out of East Carolina, he immediately became one of the league’s most productive backs, topping 1,000 rushing yards in each of his first six seasons. He missed only one game in that stretch, sitting out the regular season finale of his rookie year because Tennessee had already clinched the AFC’s top seed.
His biggest year came in 2009, when he entered the 2,000-yard club with 2,006 rushing yards in 16 games. That made him the sixth player ever to do it and one of just nine in NFL history to reach that milestone.
Johnson added 50 catches for 503 yards that season, and his 2,509 yards from scrimmage remain the league record. The performance earned him Offensive Player of the Year honors and the CJ2K nickname.
After six seasons in Tennessee, Johnson played for the New York Jets in 2014 and spent the final three seasons of his career with the Cardinals. He retired from the NFL in 2018. In 2024, he was inducted into the Tennessee Sports Hall of Fame.
Johnson said he had mostly stayed out of the spotlight since retiring, living a regular routine that included daily workouts and time with Brittany and their four children. That support, he said, has been crucial.
“She hasn’t left my side through any of this,” Johnson said. “My kids are also a huge part of why I keep going.
Every day, I wake up wanting more time with them, to make more memories and to just be their dad. They give me a reason to keep fighting.”
After seeing Dr. Merit Cudkowicz on television, Johnson reached out to the neurologist known for her ALS research. That connection led him to experimental treatments, including a clinical trial that decreases inflammation and, Cudkowicz said, was very helpful.
Johnson said he wants people to understand that ALS does not change who someone is on the inside.
“People sometimes look at the physical disability and assume you’re not still the same person inside,” Johnson said. “I still think the same; I still dream; I still love my family. My body just doesn’t cooperate.”
He said he is working with doctors in hopes of helping move toward a cure, and he has made his choice about how he plans to handle what comes next.
“Honestly, I don’t know if you ever fully process it,” Johnson said. “At first, you’re in shock.
Then, you realize you have two choices. You can give up, or you can fight.
I chose to fight.”

Cardinals Suddenly Face A Tough Call With High Priced Pass Rusher
The Bears spent the offseason patching holes with additions like safety Coby Bryant, linebacker Devin Bush and wide receiver Kalif Raymond, but the pass rush still looks like a spot where help could be needed before the 2026 season. That has put Arizona in the discussion by proxy, since one of the Cardinals pricier edge rushers has surfaced as a possible fit for Chicago in a third-party trade idea.
It is an intriguing sort of speculation for Arizona because it turns a high-priced defensive piece into a potential offseason talking point instead of just a roster staple. The player in question is on a four-year, $76 million deal and just finished a full 17-game season with 30 tackles, 12 sacks and 13 tackles for loss, which is exactly the kind of production that can make outside teams start wondering whether a deal might be possible if the right market develops.

Carson Beck Is Already Facing The Cardinals Question That Matters Most
Carson Beck has spent the early part of his Cardinals stint doing what young quarterbacks are supposed to do: absorbing the offense, leaning on the coaching staff and stacking days of work in a system that can feel like a moving target for any rookie. The third-round pick has been in close contact with Matt Schaub and Nathaniel Hackett while also taking in whatever he can from veteran quarterback Jacoby Brissett, the kind of early classroom time Arizona hopes will speed up his development.
The wrinkle is that the bridge between the rookie and the veteran has not been as full as the Cardinals might like. Beck has said he has not spent much time with Brissett, who skipped voluntary OTAs while pursuing a contract adjustment, leaving Arizona with a familiar camp question for a quarterback room: how much can a young passer pick up when one of the key voices around him is only around part of the time?

Cardinals Fans May Finally See A Real End To The Purgatory
Arizona has spent plenty of time stuck in the same loop, with enough offensive talent and coaching pedigree to hint at progress, only to run into the same old issues when the games start counting. The setup around this group still looks familiar: there is a capable offensive mind in the building, a scheme background tied to the Sean McVay and Kyle Shanahan tree, and at least enough structure on offense to avoid total collapse. Even so, the bigger questions remain the ones that have dogged the franchise for years, especially at quarterback, along the defensive front, and with a schedule that does not appear to offer much relief.
Jacoby Brissett can keep the offense functional and maybe help Arizona steal a few wins, but the larger picture is why some around the team are already looking past 2026. If the season goes the way plenty of skeptics expect, the Cardinals could end up in position to make a major swing in the 2027 offseason, when the draft is expected to offer a chance at a true long-term answer under center. For a fan base that has watched too many false starts, that is the kind of opening that starts to feel less like hope and more like an actual path out. [Read more 🡒]
