COLLINGWOOD captain Darcy Moore and veteran Jeremy Howe have both suffered pre-season setbacks.
The star defenders left the track early on Monday morning with calf injuries, before scans later in the day revealed minor strains.
Both Moore and Howe are only expected to be sidelined for a couple of weeks.
Collingwood returned for pre-season training last Thursday morning following the Christmas break.
Howe experienced an interrupted second half of 2025, making it back for the preliminary final loss to Brisbane after concussion and soft tissue injuries limited him from round 16.
