HATFIELD Main have been forced to resign from the Northern Counties East League because of financial problems.
Main, one of the senior non-league club in the area for several decades, are hoping to continue in the Doncaster Senior League next season.
Manager Paul Ward took the club to the brink of promotion to the Premier League last season before a late slump led to them finishing in fifth place.
But he has now left to join Des Bennett as joint manager of leading rivals Armthorpe Welfare and several of the Hatfield players are expected to join him.
Hatfield, founded in 1936, won the Premier Division in 1996 but were denied entry to the UniBond League because their ground was not up to standard.
It is the second blow to strike the top soccer clubs in the region following the demise of Denaby United last year.
