With Darcy Gardiner making a quicker than expected return at the weekend, and Claye Beams and Ryan Harwood getting through their comeback matches in the NEAFL, the Lions have a near full list to choose from.

Gibson is starting back with skills training again and is on track to play what could be a farewell game before the end of the season.
