The Hawthorn backline has copped two further hits on the back of the side's loss to Fremantle at UTAS Stadium on the weekend. 

Changkuoth Jiath (knee) and Jack Scrimshaw (concussion) both finished the game on the bench and, while Scrimshaw will begin to work his way through the concussion protocols, the outlook for Jiath's stint on the sidelines may be even more grim.

Physical Performance Manager Luke Boyd had this to say on the defensive duo.

"As we saw on the weekend, Jack was subbed out of the game in the second quarter after receiving a knock to the head.

"The concussion wasn't definitive at the time, it was quite difficult to assess, but obviously with anything around the head, we want to exercise caution so he was subbed out of the game.

"In follow-up tests on Monday, it has been confirmed that it was a concussion - he had some symptoms on Monday - which will mean Jack will now enter concussion protocols.

"On a positive note though, Jack was able to start jogging today (Tuesday).

Looking for proof of Hawthorn's quality in youth?

"Unfortunately CJ has sustained a PCL injury to that knee.

"Generally with a PCL injury, we don't get much change in six-to-eight weeks, even for the lower grade ones so that will mean he will not be available to play for the remainder of the season.

"On a positive note, we don't anticipate this being a long-term issue for CJ and we think he will recover quite well from the injury."
