Though the Dallas Tornado had won the NASL's 1971 Hoc-Soc Tournament[1] and the Atlanta Apollos staged two league sanctioned pilot matches at the Omni in 1973,[2][3] the birth of the modern game in North America can be traced to 1974, when three indoor exhibitions against the touring Soviet Red Army of Moscow club took place.

Much like hockey, matches were played in three 20 minute periods, allowed free substitution, and featured six man sides (five field players and a goalkeeper).
