Essendon ruckman Matthew Leuenberger has been sidelined early in the Dons' final pre-season hit out.
Leuenberger was spotted on the bench in Essendon's clash with Geelong in Bendigo with ice on his hamstring.
An injury will leave the Dons light on in the ruck, with Tom Bellchambers managing a knee issue.
Rookies Shaun McKernan and untried Sam Draper are the other options.
Essendon coach John Worsfold confirmed the injury, but did not know the severity.
"Yeah, I'm no expert on that," he said.
"We'll have to wait and see, but hope for the best."
The ruckman will have less than two weeks to prove his fitness before Essendon's round one clash with Hawthorn on March 25.
