Carlton will bring in fresh blood for Saturday's Round 21 match against Richmond at the MCG, naming 19-year-old Nick Graham to make his debut. 

Graham's inclusion is one of five changes to the Blues' line-up. 

Chris Judd, Matthew Watson and Jeff Garlett have all been ruled out through injury, while Jaryd Cachia and Sam Rowe have been omitted. 

Mitch Robinson, Andrew McInnes, Levi Casboult and Tom Bell have earned recalls, after impressing in the VFL. 

While Matthew Kreuzer will spend another week on the sidelines as he continues to recover from a minor calf injury.
