West Coast coach Adam Simpson says he expects defender Jeremy McGovern to miss multiple weeks with his latest hamstring injury.

McGovern re-injured his left hamstring in last week’s 14-point loss to Hawthorn, with the full extent of the injury to be known by Tuesday afternoon.

Simpson said the early signs weren’t great.

“I would assume he’d miss multiple weeks,” Simpson told Perth radio station 6PR.

Two-game defender Tom Barrass is expected to replace McGovern.

The Eagles will also be without star forward Mark LeCras for Sunday’s western derby against Fremantle.

LeCras was slapped with a one-match ban for his clumsy head-high bump on Hawks defender James Frawley.

Simpson says he’s still unsure whether star ruckman Nic Naitanui will be able to play against the Dockers.

Naitanui flew to Fiji last Saturday following the death of his mother.

“He’s in Fiji at the moment and needs to arrange the funeral,” Simpson said.

“We need to get the balance right between respecting his family and what he’s got to go through, and how quickly we can get him back.

“We’ve backed away.

“We’ll leave it up to him and his family to go through the right procedures, and then we’ll act off that.”

In better news for the Eagles, ruckman Callum Sinclair is on track to return from a knee niggle.

Fremantle are set to recall star midfielder Nat Fyfe (groin), while Michael Johnson is a chance to play his first game since tearing his hamstring in round 10.

All-Australian backman Luke McPharlin remains in doubt after suffering a corked calf in last week’s win over St Kilda.

The suspension to LeCras could pave the way for Tom Lamb to return to the Eagles’ line-up.

Lamb, who made a sole AFL appearance in the season-opening loss to the Bulldogs, missed a large chunk of the year after undergoing knee surgery on April 21.

But the 18-year-old has booted 10 goals in his past three WAFL matches to push his case for a senior recall.

Simpson will also consider handing a recall to Josh Hill, who was dropped for last week’s loss to Hawthorn following a decline in form.

Fremantle sit 10 points clear on top of the table, while the second-placed Eagles are now just two points ahead of Hawthorn.
