"The San Francisco 49ers family has suffered a tremendous loss today with the passing of Dwight Clark," the 49ers said in a statement. "We extend our condolences and prayers to Dwight's wife, Kelly, his family, friends and fans, as we join together to mourn the death of one the most beloved figures in 49ers history. For almost four decades, he served as a charismatic ambassador for our team and the Bay Area."
"Dwight's personality and his sense of humor endeared him to everyone he came into contact with, even during his most trying times. The strength, perseverance and grace with which he battled ALS will long serve as an inspiration to so many. Dwight will always carry a special place in our hearts and his legacy will live on as we continue to battle this terrible disease."
Clark's No. 87 was retired in 1988 by the 49ers. He revealed his ALS diagnosis in March.
