Knights down Raiders, Roberts hailed Newcastle coach Wayne Bennett was full of praise for young halfback Tyrone Roberts, but refused to anoint him as the Knights first-choice halfback. For the second successive week the 21-year-old produced an outrageous show-and-go that wrong-footed the Canberra defence, allowing him to score as the Knights sealed a come-from-behind 28-12 NRL win at Hunter Stadium on Sunday. Roberts pulled off exactly the same move in his side's win over North Queensland last Monday to justify Bennett's decision to keep him in the No.7 jersey, despite Kurt Gidley recovering from a calf injury. The Knights captain started the game at hooker before being forced off with concussion at halftime. But the seven-time premiership-winning coach said Roberts is likely to keep his spot - for now. "He sold one dummy there and I was waiting to see someone else running and he got to the line before I realised he still had the ball," Bennett said of Roberts' 51st-minute try. He does that well, Tyrone, he has that little bit of class. It's a great show and go he's got and it works for him. It confuses defenders. But no-one is No.1 for anything. He's doing a good job there at the moment and Kurt has got a head knock. Kurt only made himself available yesterday, no-one thought he was going to play and I wasn't going to change the team at that late notice. Knights five-eighth Jarrod Mullen also had a strong game and set up the opening try for Akuila Uate with a superb curling kick over the head of Jack Wighton. "He's playing well at the moment," Bennett said. He's working off the back of the forwards who are laying a foundation for them. The win was the third from four games this season for the Knights - all at home - and the coach said it was a performance his side would have failed to produce last year. "We wouldn't have done it last year, we lost our way in the first half but regrouped at halftime," he said. The most pleasing thing is we've backed it up two weeks in a row with a pretty decent performance. It was not as good as last week but it was good enough. Raiders coach David Furner was seething at his side's insipid second half display and slammed the kicking game of his halves combination Josh McCrone and Sam Williams. "Our last play options and kicking game were pretty ordinary in the second half," Furner said. "We didn't give ourselves a chance in the first half, we visited their line four times and didn't even get a repeat set, it makes it hard," Furner said. The Raiders mentor was also upset about a shoulder charge by Danny Buderus on Blake Ferguson that went unpunished. The Knights hooker poleaxed the centre, but referee Brett Suttor ruled the incident was merely a collision and allowed play to continue. "I just saw it again on the video, and I was very surprised," he said. There's been a lot of hoo-ha about this recently, and what I saw summed it up. Going off what we've been going off it was most certainly a mandatory penalty. Furner was less forthcoming about the latest antics of Josh Dugan on social media. The former Raiders fullback, who was sacked this month, saw a $2m move to Brisbane go up in smoke on Sunday after he involved himself in an ugly spat on Instagram. "I don't want to waste any more time on it, I have other problems," he said. Bennett also revealed Beau Scott would be sidelined for three months with a groin problem that will require surgery.
