West Coast coach Adam Simpson will have to wait until the historic first derby in the new Optus Stadium to be able to capitalise on superstar Josh Kennedy.

Kennedy, 30, is targeting a full return to action against the Eagles' local arch enemy in round six on Sunday, April 29.

Josh Kennedy is expected to return in the first Derby at Optus Stadium in round 6.

And West Coast enforcer Nic Naitanui will continue his emotion-charged return with a broken right thumb.

Naitanui, 27, is understood to have needed pain-killers and obvious strapping around the thumb to get through his playing resumption, after suffering the break late into his match simulation preparation ahead of confronting the Swans yesterday.
