JOSH Kennedy has delivered some concerning news for West Coast fans, declaring his comeback date could be pushed back again. 

The dual Coleman medallist was originally targeting a return in Sunday's season opener against Sydney after undergoing ankle surgery in December.  

But Kennedy's comeback was pushed back to round three, then possibly to round four after a minor knee operation to remove a bone fragment.  

Now the 30-year-old star has revealed he could be out of action for another week.     

"I'm hoping round four or five now," Kennedy told 6PR.  

"I've been running the last two sessions and I'm in full training today with the boys.  

"But because it put me back a week-and-a-bit having that (knee) surgery we're looking at round four, round five now."

Kennedy moved freely at Lathlain Park on Tuesday, twisting, jumping and kicking without any apparent issues.  

"We're doing everything we can to get the numbers and get the loading through the legs and the body," he said.

"It's been a bit disappointing obviously with that, but the ankle and the surgery from that is going really, really well. 

"The knee was a just a bit of a hiccup."

While the Eagles were boosted by Nic Naitanui's influential return against Sydney, they sorely missed their star goalkicker as Swans champion Lance Franklin ran riot with an eight-goal haul.

Kennedy's admission means he might not be sighted before the round five trip to face Carlton at the MCG.

West Coast takes on Fremantle in the historic first Western Derby at Optus Stadium the following week.    

"Obviously it was frustrating sitting up there and not being able to play (against Sydney)," Kennedy said.

"But the boys showed some pretty good spirit in fighting the way they did.

"The guys up forward played their role, which was pretty good, and we were able to get 60 inside 50s which is what we want to do as a team." 

Willie Rioli was on the track on Tuesday, allaying fears about any injury issues stemming from East Perth's thumping loss to Peel in Saturday's practice match.  

Rioli started the game without strapping on his troublesome left knee but had the leg bandaged during the first quarter.

Young midfielder Hamish Brayshaw walked laps at Lathlain Park, while Nathan Vardy (adductor), Brendon Ah Chee (ankle) and Eric Mackenzie (toe) made brief appearances with the rehab group.

Six-game defender Tom Cole was also back at training after his father's funeral in Victoria last Friday.
