However, the U.S. involvement in World War I caused the suspension of several leagues due to the loss of players to military service.
Caraffi's National Soccer Hall of Fame profile notes that he played for the U.S. Army team in Europe and this may account for those missing two years.
In 1919, Caraffi signed with the Fall River Rovers of the semi-professional Southern New England Soccer League.
The Rovers were disbanded and a new, fully professional, team, Fall River United was formed and entered the ASL.
In 1929, Caraffi joined Cleveland Bruell Insurance in the newly established Midwest Professional Soccer League.
