The Sydney Swans have been dealt with another injury blow, with co-captain Dane Rampe ruled out until at least after the mid-season bye.

Rampe hasn't played since the Round 4 loss to Port Adelaide, with Swans head medico Damian Raper saying he'll be out for an unknown timeline due to the nature of the injury.

"Dane's neck injury has not resolved. He has been reviewed by specialists who have advised that whilst the timeline for recovery remains uncertain, he is not expected to be available before the bye," Raper said.

The 32-year-old isn't the only injury concern for the Swans, with young midfielder Matt Roberts being ruled out for 8-10 weeks after injuring his knee against Geelong.

Rampe and Roberts joins Joel Amartey and Sam Reid on the mid to long term injury list, meanwhile the future Paddy McCartin remains unknown after suffering his 10th concussion.

"Paddy continues to focus on his overall recovery. He continues to improve on a daily basis," Raper said.

In some positive news, both Lance Franklin and Tom McCartin will return against the Giants, as Sydney look to bounce back from a 93-point loss to the Cats last week.
