Essendon has regained captain Dyson Heppell for its clash with North Melbourne at Metricon Stadium on Sunday, while mid-season draftee Sam Durham could potentially make his AFL debut.
After missing last week's win over Adelaide with a thumb injury, Heppell has slotted straight back into the Bombers' half-back line.
Durham joins fellow inclusions Brandon Zerk-Thatcher, Nick Bryan and Brayden Ham (last week's sub) on an extended interchange, while injured midfielder Kyle Langford (hamstring) is the only confirmed out.

The Bombers' 26-man squad will be reduced to 22 at 5pm AEST on Friday.
Should Durham be named in the 22-man team, he'll become the club's seventh AFL debutant this season.
Since crossing over from Richmond's VFL side, the 20-year old has impressed as a wingman in four VFL games for the Bombers.
