The acting captain went down in the third quarter of Sunday’s win over the Bombers, after landing awkwardly in a marking contest.
Wood was taken to hospital for scans and the club will not know the full extent of the injury until later on Monday afternoon.
However, coach Luke Beveridge conceded after the game that it doesn’t look good for the 26-year-old.
“The forecast isn’t great, unfortunately. But who knows, maybe he might be all right,” Beveridge said.
“Whether Easton is done for the year I don’t know. Hopefully it’s not too bad and even if we lose him for a week or too, hopefully we can go a bit deeper (in finals) and he might be able to re-join us.”
