Steve is held in high regard by the Forest faithful after spending 13 years at the City Ground where he is considered a hero.

As players and managers came and left, Chettle stayed with the club, and notably played alongside such Forest greats as Des Walker, Stuart Pearce, Nigel Clough, Ian Woan, Steve Stone, Mark Crossley, Stan Collymore, and Pierre Van Hooijdonk.

In July 2002, two months after his release from Barnsley, Chettle and fellow Tykes defender Darren Barnard joined league rivals Grimsby Town on one-year contracts.

Chettle was seen as an ideal candidate to step in the centre of defence and started the season alongside the club's player-manager Paul Groves and Jamaican youngster Simon Ford.

Steve eventually returned from injury in early 2003, and went on to score his only goal for The Mariners in a 4–1 home defeat against Crystal Palace.

Several months after his departure from Blundell Park, Chettle acted upon an offer to work with Nigel Clough, the son of his former Forest manager, and sign with Conference National side Burton Albion.

Chettle featured at centre back that season with notably forming a formidable partnership with long serving ex Grimsby defender Mark Lever.
