Fremantle will soon lodge paperwork with the league in an effort to move youngster Sebit Kuek to the long-term injury list as the 23-year-old recovers from knee and shoulder surgery.

Kuek will also be joined on the sidelines by former Sun Josh Corbett after the Dockers put a line through the forward earlier in the year following a nasty hip injury.

In line with Kuek, Corbett will go under the knife next week, with the Cockburn based club to lodge paperwork with the league on Monday.

Kuek went down with the initial knee complaint when featuring for Peel Thunder in July, and though the mid-season draftee is yet to see senior action for Justin Longmuir's side, the key forward prospect impressed, bagging 21 goals from 10 starts in the WAFL.

“It's unfortunate for Sebit and Josh, who have both had promising starts since arriving at the Club,” Freo list boss David Walls said within a club statement on Friday.

“Josh and Sebit's long term health is our priority and the Club will support them with their rehab while getting back to being able to play.

“We're losing two talls with Sebit and Josh having long-term injuries and that also gives us the opportunity to have four train-ons.

“We'll look at a few different types there. A couple of talls and some small forwards as well.”

While the Dockers are yet to finalise which players will be afforded the right to train for a rookie list spot ahead of the pre-season supplemental signing period opening on Monday, Woodville West-Torrens product Max Beattie and former Bomber Patrick Voss have been raised as live chances.

Fremantle's first-to-fourth-year players reported for pre-season duty on Friday.
