The Philadelphia Field Club, also known as Philadelphia F.C. was an inaugural club of the American Soccer League based in Philadelphia, Pennsylvania. Before the season, the owners of the powerful Bethlehem Steel F.C. decided to disband the club and form Philadelphia F.C. The club re-signed most of the top players from Bethlehem and players from elsewhere. Not surprisingly the team won the first ASL championship. After the season, the management broke up the team selling many of its top players due to financial trouble and lack of support. The team then returned to Bethlehem.
After the first Philadelphia F.C. returned to Bethlehem, a new team also called Philadelphia Field Club joined the American Soccer League for its second season. The new team was the polar opposite of the powerful Bethlehem languishing at the bottom of the table
After the 1926/27 season, the team was bought by new management who bought top talent from Ireland and renamed the club Philadelphia Celtic. The spending spree left the owners in financial straits and the club went bankrupt and were suspended by the league after playing only 10 games in the first half of the 1927/28 season.
The Bridgeport Bears joined the American Soccer League in the fall of 1929. After only six games the team moved to Philadelphia to become another Philadelphia Field Club. They played eight more games before the season was suspended due to the merger of the ASL and the Eastern Soccer League.
