25. for Penrith is Pobjie as we can see him scoring a try, whilst other replacements for Penrith wear 16 & 17.
Easts had replacements wearing 26. (I think Garland) & 27.

Perhaps a Penrith & Roosters supporters can be better identifiers than me.
I think Easts 26 is Joe Fenech & 27 Ernie Garland I don't see Kel Judd or Ron Gibbs. Not sure about 16 7 17 for Penrith.
