Moulton Harrox saw off Pinchbeck United to reach the quarter-finals of the Lincolnshire Junior Cup.
Harrox went through thanks to first-half goals from Joe Townsend and Billy King, although manager Paul Kent felt his side deserved to win by more.
He said: “We played well in the first half and should have been four or five up.
“We should also have been given another penalty as one of their players rugby tackled our guy, while their player should have been sent off when conceding the penalty we were given.”
That penalty came when on the half-hour mark when King converted after Townsend was brought down, having opened the scoring with a well-taken goal after 20 minutes.
Tom Gosling was later sent off for Pinchbeck in a game which saw six other players booked.
Harrox now face in-form RM Imp, who top the Lincoln League Premier Division with ten wins out of ten.
Swineshead Institute face the winners of the Harrowby Saints versus AFC Louth clash, having edged out All Star Panthers 3-2 after extra-time.

Jack Houghton levelled on the hour mark and James Zealand hit a 35-yard left-footer in extra-time to clinch victory.
Spalding Town lost 2-1 after extra-time against Horncastle. Markus Perry scored the Spalding goal.
