Ruckman Shaun Hampson ran laps at training on Tuesday, after hurting his right knee in the dying minutes of the clash against the Brisbane Lions last Saturday.
His chances of playing received a boost when he trained on Tuesday, with Ellis confident the athletic big man would make the trip.
Jake Batchelor (hamstring tightness) and Ben Griffiths (illness) were late withdrawals from the team who defeated Brisbane last weekend and would also be in selection calculations.
Veteran ruckman Ivan Maric, who has managed just two games this season, was held out of the VFL last weekend as cover for Hampson if he wasn't passed fit.
"They had a fierce pre-season (battle) and Hammer's just come out on top and taken his spot," Ellis said of the internal ruck competition.
"But (Maric) was never going to give up.
"He has that never-say-die attitude ... it's always good to have that competition."
