Rugby league fans can watch the NRL grand final under the stars at Flagstone on Sunday.

The community is invited to a fun night out to watch the decider between South Sydney and Penrith.

The night gets underway at 4pm, and includes mini jeeps, inflatable obstacle course with a giant slide.

There will also be a rock wall and face painting at the Flagstone Sports Field, on Flagstonian Drive.

Visitors are invited to set up picnic blankets and chairs. Local food trucks will be on hand to feed punters.

Nathan Cleary has hailed the medical people behind his shot at grand-final redemption, praising their positivity for keeping his NRL season alive.

The Penrith co-captain breathed a massive sigh of relief on Sunday after avoiding a charge for his lifting tackle on Melbourne forward Kenny Bromwich, leaving him free to play in the decider.

However concerns remained for the Panthers on Monday, with forwards James Fisher-Harris and Tevita Pangai both set for scans on injured knees.

Late-season recruit Pangai is believed to be the main worry, amid fears medial ligament damage could rule him out of the decider.

At least the Panthers now know they will have their star halfback on deck on grand final night, a prospect that looked in doubt after he injured his shoulder in State of Origin II.

Cleary's availability is crucial to the Panthers in the decider. He has won 19 of 20 games at all levels this year.
