Jake Carlisle is set for an extended period on the sidelines, undergoing back surgery today.

The 29-year-old has been managing ongoing lower back soreness for several weeks, with surgery expected to provide longer-lasting relief.

"We’ve been working with Jake on treatment plans, however his level of day-to-day pain and restriction of movement has gotten to a point where lumbar disc surgery is the best option," Chief Operating Officer Simon Lethlean said.

"The delicate nature of spinal injuries means it’s pretty hard to put a timeline on recovery.

"Our doctors and physios will work with Jake throughout his rehab, and we’ll monitor his progress. 

"While it’s a disappointing outcome, Jake’s long-term health and overall wellbeing is paramount."

Carlisle has played four games in the 2021 season, including his 150th AFL game.
