Dwight Clark has passed away at the age of 61 after a lengthy battle with ALS.

Clark announced his diagnosis in March of 2017.

Clark was a two-time Pro Bowler and best known for his game-winning catch in the 1981 NFC Championship Game.

I’m heartbroken to tell you that today I lost my best friend and husband. He passed peacefully surrounded by many of the people he loved most. I am thankful for all of Dwight’s friends, teammates and 49ers fans who have sent their love during his battle with ALS. Kelly Clark.
