Roughead will miss 1-2 weeks with a shoulder injury sustained in Saturday night’s win over Essendon.
The 19-year-old joins Adam Cooney, Dale Morris and Brad Johnson on the sidelines, though Johnson is a chance to take his spot in this week’s qualifying final clash with Collingwood.
Easton Wood is also a chance to return from a hamstring injury while Ryan Griffen will have to prove his fitness after injuring his knee.
Roughead had played four of the past five senior games for the Bulldogs for a total of eight for the season after usurping Will Minson as the back-up ruckman to Ben Hudson.
