The State of Origin series opener was a brutal affair but the Penrith Panthers are set to have all of their Blues representatives backing up in a big boost.

Three Panthers originally in the team’s 17 on Tuesday have been named in Penrith’s NSW Cup side on Sunday though, with mass changes expected at the foot of the mountains.
