Keith Fahnhorst, an offensive tackle on the 49ers first two Super Bowl teams, passed away earlier this week, the team announced Thursday. He was 66.
No cause of death was listed in the 49ers announcement. Fahnhorst encountered health issues after his retirement, and in a 2015 49ers-produced video, he said he learned he had either primary progressive multiple sclerosis or Charcot-Marie-Tooth neurological disorder.
The 49ers lost another franchise legend only eight days prior to Fahnhorst’s death as Dwight Clark passed away from ALS at age 61.
Fahnhorst played the second-most games (193) of any offensive lineman in 49ers history during his tenure from 1974-87.
