In 1966 several groups of entrepreneurs were exploring the idea of forming a professional soccer league in United States. One of these groups, United Soccer Association (USA) led by Jack Kent Cooke, selected 12 cities for team locations and Weston Adams,[1] owner of the Boston Bruins, was awarded the Boston franchise. The USA originally planned to start play in the spring of 1968; however the rival National Professional Soccer League, which secured a TV contract from CBS, announced it was ready to launch in 1967. Not wanting to let the rival league gain an advantage, the USA decided to launch early. Not having secured any player contracts, the league imported teams from Europe, Brazil, and Uruguay. Shamrock Rovers F.C. of the League of Ireland were brought over to represent the city of Boston.[2][3]
Rovers opened the season at home against the Detroit Cougars[a] in a 1 – 1 draw. A disallowed goal by the Cougars due to an offsides call led to an argument with the linesman who was hit in the face by a Detroit player.[4][5] Shamrock Rovers finished the season in last place of the Eastern Division with a record of 2 wins 3 ties and 7 loses, the worst in the league, and with an average attendance 4,171.[6]
