Penrith Panthers winger Josh Mansour has received some positive news after undergoing major facial surgery last week.

NRL.com has been told Mansour, who was originally expected to miss the rest of the season, is now expected to miss just 10-12 weeks after going under the knife at Nepean Hospital.

It was feared Mansour, who suffered five facial fractures after copping an accidental knee to the head from Anthony Don a fortnight ago, may had played his last game for the Panthers in the win against the Gold Coast Titans.

However, Mansour didn't require a bone graft and is now likely to return to the paddock after this year's State of Origin series.

The Panthers have been decimated by injury over the opening eight rounds of the Telstra Premiership, but have managed to overcome the crippling toll to climb to second on the ladder.

Fullback Dylan Edwards may return from a dislocated shoulder in six weeks, however he will see a surgeon on Monday afternoon to determine whether he requires surgery that will see him miss a large chunk of the season.

Dallin Watene-Zelezniak is likely to shift to the fullback role in his absence, opening the door for either Tyrone Phillips or Tom Eisenhuth.
