Cinderella got her ticket to the ball but Jarryd Hayne won't be rushing to pick up his tuxedo just yet after the Parramatta sensation was put on report in the Eels' 22-12 preliminary final win over the Bulldogs on Friday night.

The win catapulted the blue and golds into their first grand final since 2001 but it will be a nervous wait for Hayne and hooker Matt Keating.

The pair put their grand final appearances in jeopardy after both were put on report in the four tries to two win.

Hayne - who collected Bryson Goodwin with a knee to the head as the Bulldogs winger scored the opening try after four minutes - didn't seem too concerned though.

"We were both just going for the ball and I probably didn't get in the best position to get out of it," Hayne said.

"There was nothing else I could do."

Eels coach Daniel Anderson was also confident the Dally M medal winner would be right to face the winner of Saturday night's Melbourne-Brisbane preliminary final.

"It was a little clumsy but not malicious at all - we'll wait and see," Anderson said.

"There's always going to be a little bit of concern but the boys should enjoy the moment - it's a tremendously proud achievement for them so far - one game to go."

The Eels only secured victory in front of a finals record crowd of 74,549 at ANZ Stadium when five-eighth Daniel Mortimer - who had been in doubt right up until kick-off with a hip injury - finished off a brilliant movement nine minutes from time.

Parramatta have now won ten of their last eleven matches in a blistering finish to the year.

"Why shouldn't there be?" Nathan Hindmarsh said of celebrations after the fulltime siren.

"We've come from eighth, we're in the grand final.

"I know we haven't won anything yet and deep down we've come from pretty much nowhere to be in a grand final."

Hayne's indiscretion saw Hazem El Masri get a shot at an eight-point try but the winger failed with his conversion out wide before he nailed the one in front of the posts for a 6-0 lead.

Goodwin shrugged off the effects of the head knock, which was more than could be said for teammate Luke Patten who failed to see out the second minute of the match when he fell victim to an accidental knee from Eels skipper Nathan Cayless.

But having dished out the punishment, Cayless soon joined Patten in making the slow walk up the tunnel as he hobbled off with a hamstring injury to leave him in doubt for the grand final.

And the game was yet to reach its tenth minute.

The calls started going Parramatta's way, with a dubious Hayne 40-20 and a crucial scrum feed going in their favour, but still they could find no way through the Bulldogs' wall.

Something had to give, and as has been so often the case during Parramatta's stunning late season charge, Hayne did the giving as he swivelled through three defenders to lay it on a platter for Joe Galuvao and a 6-all scoreline just before the half hour.

A Ben Roberts grubber gave the Bulldogs back the lead with Josh Morris touching down after Hayne had been cleaned bowled by a horrid bounce.

Then Keating found himself in trouble after wrenching the arm of Ben Hannant just out from the break, the double reporting leaving Bulldogs coach Kevin Moore fuming.

"You've got a reporting system in place but you don't get a lot of benefit out of it," Moore said.

"Bryson Goodwin was pretty much in Disneyland for something that was pretty dodgy I thought and we've got a front rower comes off with a partially dislocated shoulder for something that was very dodgy."

But the Keating blow was nothing compared to the double strike after halftime, with Luke Burt closing the gap to two with a try out wide before Tim Mannah crashed over for his first NRL try to give the Eels a lead they would never relinquish.
