Tim Membrey is expected to be available for next month’s season opener following minor knee surgery, but the Saints are likely to be without Zak Jones due to an Achilles injury. 

Jones has faced an interrupted pre-season managing a calf strain, but has had his return to full training delayed by the latest setback. The father-to-be is expected to miss just the one game pending no further aggravation.

Meanwhile, Membrey has recovered well after a minor clean-out on his knee last Friday.

“Tim has pulled up as we hoped following a minor procedure on his knee last week,” Acting General Manager Football Operations David Misson said.

“There has been no swelling in or around the knee following the operation and he already has a good range of motion, so we’re optimistic that he will be ready for Round 1.

“Zak has faced a frustrating pre-season with injury to-date, but we’re backing him in to attack his rehab and make himself available after our match with Fremantle.”

Key forwards Max King (shoulder), Jack Hayes (foot) and Isaac Keeler (knee) are anticipated to return after Round 6, with the former to be eased into contact training within the month.

Keeler has continued to build his running loads after a tendon strain last January, while Hayes has taken part in light strength work as he closes in on a return in the coming weeks.

Matthew Allison’s foot injury will see him out of action until at least the bye, while Category B Rookie Angus McLennan will join fellow draftee Olli Hotton on the sidelines for the same amount of time with a back stress fracture.

Finally, ruckman Tom Campbell has overcome an Achilles flare-up in time for Friday’s match simulation against Melbourne.
