Collyard turned pro with the Kansas City Blues in 1971-72 and spent three seasons in the Blues' system. In 1973-74 he was called up to St. Louis for what would turn out to be his only NHL experience - 10 games and scoring 1 goal and 3 assists.
The Washington Capitals selected him in the 1974 NHL Expansion Draft but he never played for them. Instead Collyard played five seasons for the Philadelphia Firebirds from 1974 to 1979. He also played for the United States in the 1978 and 1979 World Championships.
