An attempt to free Ben Marschke from a two-week suspension has paid off with the fourth-string Sydney Roosters hooker found not guilty of a crusher tackle at the NRL judiciary.

The 23-year-old successfully had his grade one charge for a crusher tackle on Cronulla's Mawene Hiroti overturned.

The move to challenge the charge was seen as a desperate move from the club to free him to play Melbourne on Friday after they were hit with a crisis of available dummy-halves.

Last week skipper Jake Friend was forced to retire after repeated concussions, while replacement hooker Freddy Lussick underwent surgery on a fractured arm.

Second-string No.9 Sam Verrills is still at least three weeks away from a return from an ACL injury.

However, in the midst of the bizarre shortage of hookers at the club, Friend outlined his plans to help develop dummy halves at the Roosters.

The 31-year-old is working with Verrills, while the details of Friend's role at the club are still being finalised.

"I definitely want to do my bit with the young dummy-halves at the club," Friend told Sky Sports Radio on Tuesday.

"I'm already working with Sammy Verrills, he's due back in a few weeks and he's going to be very important at the back end of the year with some young halves in the side.

"Hopefully there's a role there for me somewhere next year."

Friend was forced to retire last week on the unanimous advice of several doctors after repeated concussions.

And while he understands it's the right decision for his long-term health, the Queensland Origin hooker said he felt he had more to give as a player.

"I didn't want to go and work in a coffee shop or be a plumber just yet ... that's footy," he said.

"There's plenty of blokes who finished a lot earlier than I did and I'm grateful I played as long as I did."
