Dwight Clark, whose 1982 touchdown catch in the back of the end zone is the most iconic moment in 49ers history, announced Sunday he was suffering from ALS.
The longtime 49ers wide receiver wrote that he first started experiencing symptoms in September 2015 when he felt a weakness in his left hand. Clark, 60, said he thought the sensation was related to neck pain he's dealt with since his nine-year playing career ended.
Further testing revealed he had amyotrophic lateral sclerosis, an incurable neuromuscular disease that impairs the muscles needed move, speak, eat and breathe.
