Pro hockey career
Cairns was drafted by the Kansas City Scouts in the second round of the 1975 NHL Amateur Draft. He was also selected by the Michigan Stags in the second round of the World Hockey Association (WHA) Amateur Draft in that same year.
His professional career was short lived. Cairns bounced around the minors and got called up playing just seven games in the National Hockey League wearing Jersey #20 for the Kansas City Scouts. He would end up playing two more games for the Rockies after the Scouts moved after poor season ticket sales in Kansas City.
In Colorado Don Cairns would attain his only NHL point, an assist. He retired from hockey after the 1977 – 1978 season.
