Hawthorn has confirmed the extent of Harry Morrison's hamstring injury, stating that the much-improved winger will miss a month of pre-season training.

The club announced on Tuesday afternoon that the rising conduit would be sidelined for the next month, effectively ruling him out of Hawthorn's pair of pre-season fixtures.

Sam Mitchell's side will face Geelong at GMHBA Stadium in an unofficial hitout on Thursday, February 23 before playing host to Collingwood in Launceston on Thursday, March 2.

With over six weeks until Hawthorn is scheduled to face Essendon at the MCG in Round 1, Morrison has ample time to retune and return before the 2023 season starts in earnest.

The Hawks have already conceded they'll likely be without star forward Mitch Lewis to begin their 2023 campaign, with the key-position Hawk suffering a sprained ACL following a training mishap last week.

Lewis' setback added to the small contingent of Hawks currently battling ailments of their own, with midfield pair Josh Ward (hip/groin) and Conor Nash (knee) enduring interrupted pre-seasons.

Sam Mitchell's midfield stocks took yet another hit, after Morrison hobbling off the training track on Monday.

Within vision captured by CODE Sports, Morrison is seen in dismay as he limped off the field following the club's match simulation session.

The 24-year-old had ice applied to his hamstring following the injury, with further assessment taking place after training.

Morrison was among a handful of Hawks to impress under Sam Mitchell last year, with the Benalla product playing 21 games in the brown and gold for an average of 19.19 disposals per outing, commonly featuring as a wingman.

Hawthorn is set to travel to Morwell in regional Victoria on Tuesday for a pre-season training camp, with Morrison's attendance now up in the air.

Midfield-forward hybrid Chad Wingard was reported to be left out of the match simulation hit-out as the club balances his workloads, while key defender Denver Grainger-Barras was away from training due to illness.
