[3] After battling a persistent groin injury, he was later loaned out to Port Vale and Stockport County, before entering non-League football with Scarborough and Worksop Town.
Cammack had made 36 league appearances during his four years at Bramall Lane but later claimed that "Jimmy Sirrel came in at Sheffield, and I wasn't Scottish enough for him.
Under the stewardship of Arthur Cox, Chesterfield finished 18th in 1976–77 and ninth in 1977–78, before narrowly avoiding relegation by one place and four points in 1978–79.

He found life at Lincoln difficult, however, still commuting from Scunthorpe after a proposed house move fell through and falling out with "Imps" manager Murphy, amid allegations that he was being played out of position.
