The Eels are capable of almost anything this season with Hayne calling the shots at fullback.
But without him, the electric Eels are devoid of spark and direction - winning just four out of 23 matches over the years.
Nonetheless it was another impressive performance from the Panthers, who further cemented their place in the NRL top three with a third straight win - thanks to the blossoming attacking combination of spine players Peter Wallace, Matt Moylan, Jamie Soward and James Segeyaro - the latter two scoring tries.
Moylan's instincts with his halves are growing sharper by the game, and he almost scored a brilliant try chasing through a Soward bomb - only to be collared high by Hayne's replacement Justin Hunt and dropping the ball.
It was scenes similar to when St George Illawarra's Jamie Ainscough tackled Melbourne's Craig Smith high in the 1999 grand final to give away the penalty try which sealed the Storm a premiership.
But there was no penalty try to Moylan because he didn't have control of the ball when the contact was made, and Soward instead potted the penalty goal points for a 14-0 lead.
There were injury worries for both sides - the Eels have Nathan Peats and Darcy Lussick needing scans on knee injuries, while the Panthers lost Dean Whare and Sam McKendry also to leg problems.
Parramatta's Mitchell Allgood was put on report for a dangerous throw.
