Fremantle might be left with just one genuine ruckman available for Round 1 after draftee Josh Treacy was offered a two-match ban for striking during a WAFL practice match over the weekend.
While playing for Peel Thunder, Treacy struck Perth's Brady Grey in a tackle in the first quarter, prematurely ending his day.
There was no report laid at the time, however, Perth issued a "Notice of Investigation" post-match which resulted in the WAFL Match Review Panel on Monday afternoon reprimanding the youngster.
The incident was graded as intentional conduct, medium impact and high contact.
Treacy, who was recruited by the Dockers with Pick 7 in last year's draft, was firming to make his debut in Saturday's season opener against Melbourne.
But now the Dockers' big man stocks have been left very thin as the 18-year old faces two weeks on the sidelines.
Rory Lobb is set for a lengthy stint on the sidelines after straining his ACL, while Sean Darcy is racing the clock to be fit for Round 1 with his own knee issue.
It leaves 22-year old Lloyd Meek to debut this weekend and lead the ruck division for Justin Longmuir's team in the early parts of the season.
The untried pair of Treacy and Meek looked set to share ruck duties with Darcy sidelined as they AAMI Community Series clash against West Coast.
Fremantle have until 3pm Tuesday to challenge the ban.
The Dockers open their 2021 campaign against Melbourne on Saturday afternoon at the MCG.
