NSW selectors may feel differently but Wayne Bennett says the prospect of losing strike centre James Roberts to injury does not faze him.

Roberts again staked his claim for a Blues spot with a sublime display highlighted by an 85m runaway try in Brisbane’s 32-18 NRL win over Penrith on Thursday night.

But the Broncos speedster’s Origin hopes appear to have been dashed by an ankle complaint with six minutes to play.

Brisbane coach Bennett said scans would reveal more this week after Roberts left the game in crutches.

However, Bennett believed the Broncos juggernaut would keep rumbling along without Roberts after moving into the top four with a fourth straight win.

“I think we are going good. We are picking up injuries along the way but we are still getting the job done,” he said.

“We lose (halfback) Ben Hunt (three weeks ago) and nobody blinks an eye because we are a confident footy team.

“That’s the way we make them at the Broncos – get on with life and get the job done.

“We lose James for a while, we will get someone else in there and we will get the job done.”

Bennett is so confident he believes Brisbane can even overcome their biggest hurdle: the dreaded State of Origin period.

He said their depth and 6-3 season start had them in an ideal place to not only survive but thrive without their Origin stars.

“We are in a good position,” he said.

“We are playing good football. We haven’t had a bad game all season, we are committed and we can improve.

“That’s always the biggest room in the house – room for improvement.”

Brisbane set up the win by racing to a 22-0 halftime lead, scoring four tries including Roberts’ 18th-minute stunner.

He pounced on a spilt Isaah Yeo ball then showed why he is considered the NRL’s fastest man, pinning the ears back to outsprint three Penrith defenders and become the league’s equal-top tryscorer with eight.

“I don’t think many other people in the competition would have scored that,” Brisbane skipper Darius Boyd said.

“That’s Jimmy’s speed and he is very strong for his size, he has been doing that a lot lately.”

However, disaster struck for Roberts in the 74th minute thanks to friendly fire.

His ankle was injured when his leg crashed heavily into teammate Matt Gillett in a tackle.

Boyd believed the once-troubled Roberts was in the right headspace to deal with the setback.

“He has been playing great footy and happy around the club,” Boyd said.

“It’s just good to see James in that good space.”
