Manly bosses will meet NRL chief executive David Gallop on Wednesday to discuss the behaviour of Sea Eagles players at their season launch which resulted in two allegations of assault.

Star fullback and NRL poster boy Brett Stewart faces sexual assault allegations from a 17-year-old neighbour while Test forward Anthony Watmough is now accused of punching, not slapping, a club sponsor.

Stewart fronted Manly court on Tuesday where an apprehended violence order against him was extended until April 7.

Police are continuing investigations into the allegation of sexual assault at North Manly on Friday evening.

Meanwhile the club sponsor who was involved in an altercation with Watmough claims the player punched him after he confronted him over inappropriate comments made towards his 21-year-old daughter.

It is a further dent to the Sea Eagles' off field reputation as club chief executive Grant Mayer and chairman Scott Penn prepare to meet Gallop to present a report on the events of last Friday.

The NRL is likely to heavily sanction the Sea Eagles with a hefty fine after concluding their own investigation.

Comments on Tuesday about Watmough's behaviour at the Wharf Bar following the club launch are unlikely to help Manly.

Neither are the thoughts of co-owner Max Delmege who claimed there was "limited" food at the function and that "in retrospect, I think our events manager picked the wrong venue."

The man alleged to have been assaulted by Watmough told Fairfax radio he confronted the player because he was harassing his daughter at the Wharf Bar.

"He punched me. It wasn't a slap. It was a punch," said Paul, who did not give his surname, from P&T Structural Landscaping.

"He was just being ... I don't want to get into the wording. It was not very nice.

"She is a young 21-year-old, very attractive lady and she did not need to be spoken to the way he was speaking to her.

"He was just very rude and that's what sparked me to get up and then he hit me."

Paul said he told Watmough to calm down and sit down but "he just wouldn't take that as an answer".

Watmough had an apprehended violence order taken out on him in June 2007 by his ex-girlfriend.

That AVO was removed four months later as both parties reached a written agreement.

Watmough's former partner Gillian Rixon had accused him of a string of violent attacks during their seven-year relationships, claims denied by the player.

While Watmough apologised to Paul for their altercation over the weekend, the club sponsor believes the Sea Eagles need to reprimand the 24-year-old Test forward.

"I think there needs to be a little bit of discipline and a little bit of reprimand, otherwise they think they can do whatever they like," he said.

Paul said he would continue to be a supporter and sponsor of the Sea Eagles, but was yet to decide whether to press charges against Watmough.

"I have not even given a formal statement yet. The police want me to. It's just something I have to think about," he said.

"At the end of the day, we'd both had a few drinks.

"I'm not holding any grudge, but I'd just like to set the record straight."

The club sponsor however supported the behaviour of the "majority" of the players at the function, adding his support for embattled star Brett Stewart who is facing sexual assault allegations from later in the evening.

"He would have to be the most delightful person I know," said Paul.

"I have never found a more nicer gentleman, he is a gentleman."

As expected both Watmough and Stewart were named in the Manly side to face the Bulldogs at ANZ Stadium on Saturday night.

There had been pressure for the Sea Eagles to stand Stewart down, but the club remains adamant he will play unless charges are laid or he is not mentally ready.

Stewart's lawyer Geoff Bellew, who represented the player in court, said the AVO did not prevent his client from returning home.

"If he wants to (go home) he could, but he doesn't want to," Mr Bellew said.

"He's moved away from there."
