Five games into Todd's second season, shortly after he turned 18, a pack of players collapsed on his left leg during a match. Todd suffered a torn anterior cruciate ligament that was unable to be repaired with the medical techniques of the time. Wearing a special leg brace he was able to continue playing but only had two more seasons in his career that were not affected by injury. He won the South Fremantle best and fairest award in each of these years, 1958 and 1961 and also was selected in the All-Australian Team following Western Australia's successful 1961 Brisbane Carnival performance. Todd played a total of thirteen state games for Western Australia between 1955 and 1962, kicking 25 goals.
