The NRL salary cap will rise to $4 million from next season after club chief executives agreed to the increase at a meeting with the NRL.

Club bosses supported the Rugby League Professionals Association push to lift the cap from the current base figure of $3.36 million at Thursday's chief executives' meeting.

RLPA president Simon Woolford welcomed the news and expected there to be no hitches in the NRL signing off on the deal next week.

"I would expect a handshake agreement on the salary cap on Tuesday," Woolford said.

"There's a lot of positives to come out of reaching an agreement on the cap ... it will be the start of a really good working relationship between the NRL and RLPA.

"On top of that, the clubs need to know next year's cap so they know how they can spend their money from June 30."

NRL chief executive David Gallop said he was pleased the RLPA had scrapped plans to shoot for a $5 million salary cap.

"The clubs supported the new position which includes a further lift in the cap and the club grant," said NRL chief executive David Gallop.

Meanwhile, player manager Gavin Orr's future in rugby league is in serious doubt after club bosses supported compulsory player manager accreditation.

Paul Osborne, the NRL agent accreditation scheme's chief operating officer, has been pushing hard for compulsory accreditation, which would effectively end the involvement of unaccredited managers in the NRL.

"It will mean they can't be involved in negotiations, can't sign a contract, they effectively won't be able to operate in the industry," Osborne said.

"I had a meeting with the player managers a couple of weeks ago and they all supported the move.

"That means all four - the managers, the players, the clubs and the NRL - support it.

"You can read from that it will happen, and hopefully very quickly."

Orr, the manager of Sonny Bill Williams, has already been denied accreditation, following allegations he forged the signature of Parramatta forward Fuifui Moimoi.

The accreditation of leading managers George Mimis (Mark Gasnier) and Jim Banaghan (Ruben Wiki) is also under review.

There are currently 31 accredited managers, with the number likely to rise to 50 in coming months.

Orr was unavailable for comment.

Other key points to come out of the meeting:

- The possibility of a cap concession for current players who take on a cadetship to become a referee

- Clubs agreed to a 25-week competition next year, with one bye for each team, following the inclusion of the Gold Coast Titans franchise in 2007.

- A more flexible McIntyre finals system which rewards higher-ranked teams with a genuine `home city' advantage

- Further investigation of a National Youth Competition to be conducted.

Elsewhere, in-form Cronulla half Adam Dykes will be out for only six weeks after a better than expected outcome following ankle surgery.

There were fears Dykes could miss the whole season had he required a pin to be inserted, but could be back in six weeks.

"We were initially looking at four to six months out, so this is good news," Sharks doctor Dave Givney said.

"Adam is the most impressive person I've ever met when it comes to personal rehab.

"He does everything according to the book, he's very diligent.

"He won't be able to run for four weeks, but if he works hard we're looking at getting him back a couple of weeks after that."

Givney also quashed rumours that Brett Kimmorley could make an early return from an ankle injury against Canberra on Sunday.

"He won't even be getting on the bus with us," he said.

"He's struggling to run and he's probably two or three weeks away."
