|Career NFL statistics|
Belden attended Central Catholic High School, where he was a teammate of future pro football hall of famer Alan Page. He became a starter at quarterback as a junior and registering a 4-3-3 record. In his final year, his team finished with a 6-3-1 record and he was named All-Ohio.
He accepted a scholarship from the University of Notre Dame, where he was the third-string quarterback behind Terry Hanratty and Joe Theismann. He tore his left medial collateral ligament during the 1967 spring practices and tore again the same ligament during the 1968 spring practices. As a senior, he was 3-for-3 in passing and 8-for-14 in his career, although he didn't reach the minimum playing time to be lettered.
Belden was selected by the Dallas Cowboys in the twelfth round (308th overall) of the 1969 NFL draft, even though he never started a game in college. As a rookie, he was able to make the team after Jerry Rhome was traded to the Cleveland Browns and Don Meredith unexpectedly retired. He was active for the first game and was placed on the taxi squad the rest of the season.
