In summer 1957, McCanless suffered a broken neck in a swimming pool accident.[4] It kept him out for the 1957 season, and McCanless was told he would never be able to play football again. Despite this, he returned to practice for his senior season in 1958 and made the final roster.[4] His first game back came in week two against North Carolina, when he was substituted in at left tackle.[4]
After graduating from Clemson, he spent 1959 as a coach in South Carolina.[5]
Professional career
In 1960, McCanless was signed by the Houston Oilers of the American Football League (AFL). He started in each of the five preseason games on the offensive line, and impressed enough to make the final roster.[6] McCanless only appeared in one game with the team before being placed on waivers and released.[5][7]
Later life
Shortly after being released by the Oilers, McCanless accepted a position as assistant football coach and science teacher at Clyde A. Erwin High School.[5] He later managed the Battery & Ignition Company in Asheville, North Carolina.[8] He also served as the Buncombe County, North Carolina, Schools transportation director for over 20 years, from 1972 until at least 1992.[9]
