The 26-year-old has been playing a valuable role in Melbourne's injury-hit backline this year.

Smith was one of the hard-luck stories of the Demons' run to the 2021 premiership after hurting his hamstring in the first week of the finals before being ruled out for the preliminary final.

Fellow defender Michael Hibberd has suffered a minor setback as the veteran attempts to overcome a persistent calf injury.

Hibberd has not played an AFL game since last year's Grand Final and will have to wait a bit longer to feature at VFL level for the Demons.

Melbourne are gunning for a 15th straight win when they play fellow top-four side St Kilda at the MCG on Sunday.
