Sydney superstar Lance Franklin has been ruled out for a second straight week with a hamstring strain.

The star forward will miss the Swans' trip to the Gabba against Brisbane on Saturday.

"He will miss another week. We're pretty confident he will be available next week," Longmire told reporters on Tuesday.

"We scanned him on Friday morning and there was a slight strain there and we looked at that and talked about it last week and then talked about it again this week.

"A limited pre-season, age and all those things come into it and we decided not to take the risk."

Franklin was a late withdrawal from the Sydney derby against Greater Western Sydney on Saturday night with the hamstring complaint he suffered at training before the match.

The Swans are hopeful Franklin will be right to resume against Essendon in round eight.

In better news for the Swans, forward Will Hayward may be fit to return for the Brisbane trip.

Hayward broke his jaw against Carlton in round three.

"Will Hayward is a chance to come back into the team this week. He will see a specialist later this week to determine that," Longmire said.

"We will be guided by the medical experts on that."
