Essendon say Matthew Leuenberger will resume full training in about a fortnight as the Bombers try to manage a lingering Achilles issue.
The former Brisbane Lions ruckman has been afflicted by persistent Achilles troubles during his injury-plagued nine year career, and has been on a reduced program early in 2016 as the Dons attempt to ensure he doesn't miss any games due to a further flare-up.
The West Australian joined the Bombers as a free agent last October after the Lions decided not to match Essendon's bid to claim the tall.
Taken at pick four in the 2006 draft, Leuenberger, 27, played 108 games at the Lions, 14 of which came last season.
Having previously been the Lions' first-choice ruckman, Leuenberger was in recent seasons displaced in the pecking order by Stefan Martin. The new Bomber is likely to battle Tom Bellchambers for the spot as Essendon's main ruck.
Meanwhile, star Dyson Heppell is back in full training after overcoming the abdominal and groin issues the Bombers say plagued the 2014 All-Australian throughout the second half of 2016.
The issue was exacerbated slightly during November's International Rules Test in Ireland, but having been placed on a modified program, Heppell is again back training with the main group, pending Tuesday's Court of Arbitration for Sport decision relating to the Bombers' supplements regime in 2012.
Already a member of the Dons' leadership group, Heppell was recently elevated to the vice-captaincy at Tullamarine and is widely viewed as the heir apparent to captain Jobe Watson.
