Toovs stands by ref attack No regrets: Geoff Toovey. Manly coach Geoff Toovey isn't backing down from his fiery post-game comments, saying he didn't question the integrity of match officials after his side's controversial loss to South Sydney. The Sea Eagles were on the wrong end of a number of controversial decisions at Gosford on Friday night, including a no-try ruling against centre Steve Matai and a first-half penalty count of 6-2 against his troops. Toovey was also critical of a Jeff Lima leg-pull on Anthony Watmough, and Greg Inglis staying down to milk a penalty for a high tackle. Speaking on Saturday, Toovey stood by his comments. "All I said was there needs to be an investigation into the performance [of match officials]," Toovey told Fairfax Media. I may question some of the decisions that were made, but I would never question their integrity. Toovey's biggest gripe was the Matai incident. The New Zealand centre appeared to ground the football over the try line. Referee Henry Perenara referred the matter upstairs but then called no try. Video referees Steve Chiddy and Matt Rodwell didn't see sufficient evidence to overturn the decision. Toovey has maintained it is pointless the on-field referee providing a ruling, as he wouldn't refer it if he was sure of the call. "There's always going to be controversy over those subjective decisions," he said. It's the ones that are in the realm of probability - that's where the controversy lies. For all money you say it's a try or not a try, yet the decision is made because the referee is not sure. He said Matai was adamant that he had grounded the football. "Definitely, you can see it," Toovey said. That's what I don't understand. The ref wasn't sure about it being held up, but you can see the ball on the ground. I don't know what they were looking at. The turning point was the Steve Matai no try and I'll be very interested to hear the explanation. That would have pushed us way ahead and we probably would've closed the match off. The former Sea Eagles, Blues and Kangaroos playmaker said an "obvious" solution to more consistent officiating was scrapping the two-referee system. "We've been down that path and that's the obvious one," he said. Last night the 10 [metre interpretation] was different, the ruck control is different. It's how it is because there are two people adjudicating on the rules. That's been the argument from Manly since they first brought it in. Why have two? The NRL will examine footage of the post-match press conference footage to decide whether Toovey overstepped the mark. Manly boss David Perry backed his coach, saying he raised important issues on behalf of the club and the game. "At no stage did Geoff challenge the integrity of the officials, in my opinion," Perry said. It's an emotional environment after such a high-pressure match. We were just seeking some clarity and resolution towards these potential issues. A lot of people are impacted by these critical calls in the game. Lima is also set to come under scrutiny. The South Sydney forward appeared to latch on to the leg which Sea Eagles counterpart Watmough had recently injured. As the matter was placed on report, the NRL's chief medical officer, Ron Muratore, declined to comment on the incident. However, he said the ARLC was monitoring the trend of "cannonball" tackles or other manoeuvres where a third of fourth defender would attack the legs of the ball carrier. "It's being looked at as we speak," Muratore said. We're satisfied we have the right processes in place to look at these things. Twitter -@proshenks
