Luckless Saint Hunter Clark has reportedly been sent for scans after sustaining his latest head knock on Wednesday.

Clark, 24, left the training track earlier in the day after copping an errant elbow from fellow St Kilda midfielder Brad Crouch during the opening 10 minutes of match simulation.

As first reported by Trent Kniese of Nine News, it is not yet known whether the former top-ten pick was left concussed in the collision or just how long Clark can expect to spend on the sideline.

However, given Clark's history with head knocks, St Kilda will certainly err on the side of caution.

Throughout his 87-game career at Moorabbin, Clark has experienced several interruptions due to head injuries, with the Dandenong Stingrays product having broken his nose, and his jaw, as well as being left concussed in several separate incidents.

The most notable of these instances came during the 2021 season when former Crow David Mackay left Clark sprawled on the surface of Cairns' Cazaly Stadium with a broken jaw.

St Kilda is yet to offer any form of comment regarding Clark's health.

The Saints will take on both Essendon and North Melbourne across the course of the pre-season before making the trip down the highway to face Geelong at Kardinia Park in Round 1.
