Key defenders Fletcher Roberts and Jordan Roughead will make their return from injury with Footscray on Saturday, named in the extended squad for the VFL side's Round 18 match at Victoria University Whitten Oval.

Roughead has missed the last three weeks with a foot injury, while Roberts has been sidelined since injury his ankle in the Club's Round 15 win over the Gold Coast Suns in Cairns.

The defensive pair will add significant experience to the Footscray back-six, and have been named to occupy key-posts in defence along with father-son defender Zaine Cordy.

The fourth placed Footscray (10-5) side take on Port Melbourne (6-9), with the standalone VFL side currently sitting just outside the top-eight in ninth position.

A win for Footscray could boost their claims for a top-two place on the VFL ladder, sitting one game behind Wiliamstown and Sandringham.

Footscray have named a squad that will feature 18 AFL-listed players. Father-son prospect Darcy Macpherson has again been named as the 23rd man.

After this weekend, just two rounds remain in the VFL home and away season, before finals beckon, commencing in the first weekend of September.

Saturday's Round 18 VFL between Footscray and Port Melbourne will be broadcast live on Channel 7, with coverage commencing from 12:00pm.
