Penrith's chances of making it back-to-back NRL wins against in-form Melbourne have received a boost with key duo Luke Walsh and skipper Petero Civoniceva considered likely starters for Sunday's Centrebet Stadium match.

The Panthers, who finally broke through for their first home win of the year with a 36-10 victory over Canberra on Saturday night, will need all hands on deck against a Storm side which has surged to the top of the NRL ladder.

Walsh came off in the dying minutes of the win over the Raiders, with his shoulder complaint linked to a muscular issue with his neck.

He failed to join the rest of his teammates in Monday's field session but is confident of taking on the Storm.

"He did some cardio work today but it's settled down a bit," a Panthers spokesman said.

"He thinks he'll be right, especially with the long turnaround from the Saturday night game."

Civoniceva was also a spectator at Monday's session after rolling his ankle against Canberra, but is considered to be in no doubt to play on Sunday.

The news wasn't so good for the Warriors with promising fullback Glen Fisiiahi ruled out for six weeks with ligament damage in his ankle and knee.

The rookie fell awkwardly in a tackle in Saturday night's win over Sydney Roosters, with his injury opening the door for Lance Hohaia to reclaim the No.1 jumper he lost after the Warriors opened the season with three straight losses.

Wests Tigers were still awaiting the results of scans on Keith Galloway (groin) and Geoff Daniela (pectoral muscle), though club officials aren't too optimistic of having the latter back on deck any time soon.

Canberra's bid to get back on track should be boosted by the expected return of Dane Tilse (hamstring) and Joel Thompson (head knock).
