Lott switched to the safety position in 1985. He had the tip of his left pinky finger amputated after the 1985 season when it was crushed while tackling running back Timmy Newsome, and a bone graft surgery would not have allowed him to start the 1986 season. An injury sidelined him for the season's last two games in 1986, but he still led the league with a career-best 10 interceptions, while recording 77 tackles, three forced fumbles, and two quarterback sacks. In his 10 years with the 49ers, Lott helped them win eight division titles and four Super Bowls: XVI (1981 season), XIX (1984), XXIII (1988), and XXIV (1989). He is one of five players that were on all four 1980s 49ers Super Bowl wins. The other four are quarterback Joe Montana, linebacker Keena Turner, cornerback Eric Wright, and wide receiver Mike Wilson.
