Dean died Wednesday night to COVID-19. He was 68 years old.
"I am heartbroken by the sudden passing of my dear friend, Fred Dean," Hall of Famer and former 49ers owner Eddie DeBartolo said in a statement released Thursday morning. "He was a humble, kind and quiet giant, with a smile as big as he was. The greatness of the 49ers truly began with Fred’s arrival in San Francisco.
"He never said very much, but when our defense needed him to make a big play, we looked to Fred and he never let us down. He leaves behind a Hall of Fame legacy both on and off the field and will be greatly missed. Our hearts and prayers are with his wife Pam, his children and his entire family."

Dean was elected into the Pro Football Hall of Fame in 2008 in his 18th year of eligibility. He spent the first six years of his career with the then-San Diego Chargers before being traded to the 49ers during the 1981 season.
The former 49ers star had 17.5 sacks for San Francisco in the 1983 season. He recorded six sacks in a single game against the New Orleans Saints that year.
