New South Wales coach Laurie Daley has vowed to stand by the players who have failed to stop another State of Origin series win by Queensland.

For the 10th time in 11 years, the Blues fell to the Maroons, who claimed an unassailable 2-0 series lead with a 26-16 game two victory on Wednesday night in Brisbane.

Daley, though, will not be using game three as a chance to experiment, insisting there is no such thing as a dead rubber in Origin.

"We're there to win — we'll be there to win game three," Daley said.

One change Daley looks like he will be forced to make is in the halves with half-back Adam Reynolds failing to finish the match due to a shoulder injury.

Reynolds will have to have his injury assessed but Daley says the initial prognosis is not good.

"I don't want to say too much but I don't think he'll be right for game three," he said.

Despite another series defeat, Daley believes his group is closing the gap on the Maroons.

But he also says near enough is not good enough and it is time to start delivering for his players.

"I believe we're getting closer. I think the players believe we're getting closer," he said.

"At some point, we'll have to draw a line in the sand and say, effort is good but we can't keep reverting back to that.

"We've got to convert and that's the challenge for us."
