McKenna played six seasons with Calgary between the 1955 and 1963. He had 88 receptions for 1,436 yards and 10 touchdowns and also saw action on defence.
McKenna set a league record with a 104-yard reception on a pass from Don Klosterman in 1955. The mark has since been broken, but remains the fourth-longest passing pass in franchise history.
McKenna, a Boston native, settled in Calgary after his playing career and worked as a geophysicist for Texaco Canada for 35 years.
He was chosen in the seventh round of the 1955 National Football League draft by the Philadelphia Eagles.
