I am trying to find a piece of information. Who was the safety for the San Francisco 49'ers who lost half a finger during a NFL game and kept on playing? I believe he is now in the NFL Hall of Fame.......but his name I can't recall.

Jimmy Johnson. He kept playing and went on to become one of the most renowned safety’s of all time, winning two Super Bowls with the Dallas Cowboys, and is currently in the Pro Football Hall of Fame.
