Essendon recruit Jye Caldwell is understood to have re-injured his hamstring at training and is facing a further spell on the sidelines as he battles the setback.
As reported by SEN's Sam Edmund, Caldwell has suffered further damage to his already hindered hamstring, an injury he first sustained in the Bombers' Round 2 clash with Port Adelaide.

Initially diagnosed to miss close to eight weeks, the 20-year-old is now facing a delayed return to the already-battling Bombers lineup.
Essendon also lost star midfielder Dylan Shiel and ruckman Sam Draper in the same weekend Caldwell suffered his setback, while veteran defender Michael Hurley continues to battle a hip complaint.
Shiel and Hurley remain multiple months away from a return while Draper could come back into selection planning for coach Ben Rutten in four weeks time.
The Bombers are currently placed 15th in the league with a 2-5 start and will be looking to improve on their record as they face the Giants on Saturday.
