Career
He entered the NFL as a walkon player with the Dallas Cowboys. He played for the Chicago Bears for seven seasons before re-joining the Cowboys during the 1974 season. During his tenure with the Bears, he scored 456 points.
With:26 remaining in the game with the score tied at 10–10, Bears returner Cecil Turner fair-caught a Packers punt at the Packers 43-yard line.
The Bears decided to kick the game-winning kick as a fair catch kick, which has rarely been done before. 4 years later, in 1972 against the Houston Oilers, Percival once again attempted a free kick.
However, this time, the kick, which was 50 yards, missed.
