Former NFL running back Chris Johnson announces on ABC’s “Good Morning America” that he has been diagnosed with amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease. Multiple outlets report that Johnson told host Michael Strahan that the diagnosis came last year and that his symptoms have progressed faster than he expected. Johnson describes the impact of the disease during the interview and addresses the speed of its advancement over the past year and the difficulty of coping with it. Several sources also note that Johnson says there is no known family history of ALS. The coverage consistently places the announcement on the same “Good Morning America” appearance, with outlets describing him as a former standout NFL running back and highlighting his status as a record-setting player. Sources differ only in emphasis—some focus on the emotional reaction and the pace of progression, while others summarize the announcement and his background—but they agree on the core facts: Johnson reveals an ALS diagnosis made in the prior year and details its rapid progression in the interview aired Monday.
