Fremantle have confirmed uncapped forward Sebit Kuek has suffered an ACL setback and will require close to 12 months in rehabilitation due to the knee injury.

Kuek, who joined the Dockers as the 14th pick in last year's Mid-Season Draft from East Perth, sustained the injury in the WAFL over the weekend against East Fremantle.

The club revealed the extent of the 22-year-old's setback on Tuesday, with Kuek requiring surgery after hyper-extending his knee.

“Sebit hyperextended his knee contesting the football for Peel on Sunday and unfortunately, scans have revealed he has torn his ACL,” Dockers football boss Peter Bell said in a club statement.

“It's really disappointing news for Sebit, who has been committed to his development at Peel and has performed at a high standard. On the back of these performances, he has signed a contract for the 2024 season.

“We'll give Sebit all the support he needs to get back on the field and back to his best.”

Kuek had booted 25 goals in his 13 games at the state league level this year before suffering the injury.

The Dockers also confirmed this week that Kuek has signed a contract until 2024, meaning he will remain with the club over the course of his contract before eyeing a return next year.

The young forward's injury adds to a tolling week for Fremantle's casualty ward, with ruckman Sean Darcy and Brandon Walker both requiring scans for respective leg injuries.

The club is yet to confirm the full extent of their setbacks, which occurred in last Saturday's loss to Collingwood.
