Penrith prop Adam Woolnough could return within 10 weeks despite earlier fears a knee injury suffered in their NRL win over Wests Tigers was set to end his NRL season.
Panthers officials feared Woolnough had torn his anterior cruciate ligament in Monday night's 30-8 upset of the Tigers, which would require season-ending surgery.
But club doctors confirmed the former Newcastle player had torn his medial ligament.
While he will still require surgery, the club is confident he will be back on the park by round 15.
Penrith also received better-than-expected news on backrower Trent Waterhouse, who is expected to miss no more than three weeks due to an ankle injury.
