Marcus Windhager has undergone surgery on his hand following a déjà vu moment against Essendon.

Almost 12 months to the day since he broke his right hand against the Bombers in last year’s AAMI Community Series, the 20-year-old left the ground early after receiving an almost identical injury to the opposite hand.

“Marcus will be touch and go for Round 1, but we’re confident this injury won’t impede his availability much further beyond that,” EGM Football David Misson said.

“One silver lining is that Marcus is very attune to the best way to rehab this injury, so we’re confident he’ll get to work and be back as soon as he can.”

On the other end of the spectrum, Hunter Clark is looking at a prolonged stint on the sidelines after injuring his calf at training on Monday.

“Hunter had graduated concussion protocols and was reintegrating back into full-contact training,” Misson said.

“Unfortunately, in a relatively innocuous moment of training, he strained his calf in a way we don’t often see.

“While we’ll have to monitor his progress, an injury like this could require a rehab period of 4 to 6 weeks.”

Zak Jones remains in concussion protocols and will resume full training next week, while Jack Sinclair continues to make his case for a Round 1 selection as he overcomes a calf niggle.

Josh Battle and Liam Henry, who both left the ground early on Friday after receiving knee knocks against Essendon, have both been given a full bill of health and will be available to face North Melbourne on Sunday.
