Essendon captain Dyson Heppell is out of this afternoon’s clash against Port Adelaide.
He was spotted heading in for scans earlier this week, with the club confirming on Saturday afternoon that back spasms will keep him out of the clash.
Martin Gleeson replaces him in the selected side, with Tom Cutler named the Bombers’ medical sub for a second consecutive week.
Port Adelaide has also made a late change, with Todd Marshall to miss with a back injury.
Fellow forward Mitch Georgiades is his replacement, while Tom Cutler has been named Port Adelaide's medical sub.
