His Formula One career began with the Tyrrell Racing Organisation in . He put in a number of aggressive and fast drives, finishing fifth in his first race in Brazil and then second in Detroit before being disqualified. At the 1984 Dallas Grand Prix Brundle broke his ankles and both feet in a crash during a practice session, and was forced to miss the rest of the season while he recuperated; the severity of the damage to Brundle's left ankle initially led doctors to consider amputating his left foot. While Brundle did recover, the damage would leave him with permanent injuries, preventing him from running and left-foot braking. Later in the year Tyrrell were disqualified from the World Championship due to a technical infringement and Brundle's achievements for that season were wiped from the record books.
