Crook were re-constituted in the summer of 1928 and after being refused entry to the Northern League, spent the 1928–29 season in the Durham Central League. They were accepted back into the Northern League in 1929, but a year later decided to turn professional and joined the North Eastern League under the name Crook. In 1931–32 the club reached the first round of the FA Cup again. After beating Stockport County 3–1 in the first round, and then defeating Aldershot 1–0 in a second round replay, they were drawn against First Division Leicester City in the third round, eventually losing 7–0 at Filbert Street. With the club virtually bankrupt after finishing bottom of the North Eastern League in 1935–36 a special meeting was called and the decision to revert to amateur status and rejoin the Northern League as Crook Town was made. The club struggled on until World War II and the Northern League closed down in 1940.
