Another member of the 49ers' first Super Bowl team, Keith Fahnhorst, passed away on Tuesday at age 66, the team announced Thursday evening.
Fahnhorst, an offensive lineman who appeared in 193 games for the team over a span of 14 seasons, died eight days after his former teammate, Dwight Clark, passed due to complications from ALS.
Fahnhorst is second only to Len Rohde among 49ers offensive linemen in the number of games played for the team.
The 49ers did not give a cause of death. But Fahnhorst battled polycystic kidney disease after he left the 49ers as well as neurological issues later in his life.
