St George Illawarra coach Paul McGregor has named his mandatory 21-man squad to face the Penrith Panthers at Panthers Stadium on Saturday, May 26 at 7:30pm.

The Dragons have maintained the same 17 that overcame the Canberra Raiders on Sunday afternoon at Mudgee's Glen Willow Stadium.

The only change to the squad overall is Luciano Leilua's inclusion in place of Mitch Allgood.

Dragons front-rower Jeremy Latimore will bring up his 150th NRL game against his former Panthers side; a team he will have played exactly half of his NRL career for come Saturday night (75 appearances).

Veteran winger Jason Nightingale will also rack up another accolade against the Panthers as he racks up the third-most appearances by a Dragon, Steeler or St George Illawarra player ever.

Nightingale's 257th first grade game will see him overtake Dragons legend Norm Provan on the combined appearances list.
