HAWK Jordan Lewis will be restricted in his training for up to three months after injuring his shoulder during pre-season training last week.

The Age reports that Lewis had surgery on the shoulder on Friday in order to repair a similar problem sustained by teammate Luke Hodge last month.

Football manager Mark Evans said that, while the injury was not overly serious, it would still result in Lewis avoiding contact drills for two to three months.

"It's one of those injuries where, if someone did it during the season, you'd let it go, but when you've got the time to fix it, you always take the time,” Evans said, noting that Lewis will join Hodge on a modified program.

"The good thing is that they can both train fully and [fitness coach] Andrew Russell will be delighted to know he can put some extra running into their legs.

“By mid-March, they should both be back into full training, which gives them a couple of weeks before the season starts.

Lewis and Hodge will join defender Trent Croad (foot) in missing Hawthorn’s NAB AFL NAB Cup matches, a situation Evans believes has an up-side.

"While we don't want a long injury list, it gives us a real opportunity to see some of our kids in the NAB Cup, guys like Beau Dowler and Mitch Thorp and maybe a couple of the draftees.

“It could work out well for us in the long run."
