Charlie Krueger (born January 28, 1937) is a former American football defensive lineman. He played his whole fifteen-season career in the NFL for the San Francisco 49ers. Previously he was an All-American at Texas A&M University and was inducted into the College Football Hall of Fame in 1982. With the 49ers, Krueger wore number 70 and his number was retired by the 49ers. He was one of the last linemen in the NFL to wear a two-bar "quarterback" facemask. Charlie's brother Rolf was also an NFL player with the St. Louis Cardinals and the 49ers.
In 1988, Krueger was awarded more than $2.3 million dollars in damages stemming from a lawsuit against the San Francisco 49ers. The judge found that Krueger received repeated anesthetic injections during his NFL career so that he could continue to play in spite of significant knee injuries. The decision found that the 49ers were not truthful with Krueger regarding the seriousness of his injuries, which left him with severe chronic pain after his playing days.
