Liberatore has undergone ankle surgery after scans revealed ligament damage, however, the Dogs are hopeful the midfielder will return before the end of the season.
“He’s come through (the surgery) really well so our plan is to get him up and running from a rehab perspective as quick as possible,” Bulldogs General Manager Football Graham Lowe said.
“We need to manage it the right way but we’re optimistic that Tom can play a key part for us towards the end of the season.”
Macrae suffered a hamstring injury, with Lowe optimistic that he too can return later in the year.
“It has got some tendon involvement which means it will take that bit longer but Jack will commence rehab in the coming days and we’re optimistic he’ll have a role to play toward the end of the season.”
