Hunter Clark will miss at least a month of football following a knee ligament sprain.

The 24-year-old was subbed out of Saturday afternoon’s game against Hawthorn after a collision in the opening term.

Scans have since shown a high-end MCL sprain to Clark’s left knee, with an expected rehabilitation period of 4-6 weeks.

“Hunter is unfortunately very well versed in the rehab process, and we have no doubt he’ll attack this period with diligence and professionalism,” Acting General Manager of Football David Misson said.

Meanwhile, Jack Bytel has been ruled out of the clash against the Swans after receiving a concussion in the VFL on Saturday.

Conversely, Mitch Owens is tracking well and hitting all required milestones as he progresses through his own concussion protocols.

“Given the quick turnaround to the Sydney game, we’ve already decided to take the pressure off Jack to be ready for that game,” Misson said.

“With Mitch, we’ll see how he is over the break, but so far he’s going well and we’re hopeful he will be available for Round 13.”
