Indigenous League star Nicho Hynes is expected to shake off his calf troubles and play in the State of Origin series opener on Wednesday after completing his most productive training session since NSW went into camp.

But Josh Addo-Carr’s hopes of receiving a Blues recall in the State of Origin series have been thwarted by a hamstring injury that is set to sideline him until August.

News of Hynes’s recovery came on the same day fullback Dylan Edwards sent a shock through Origin camp by reporting quad tightness. Axed NSW skipper James Tedesco is expected to be on stand-by for Origin I.

Nicho Hynes went through a training run on Saturday unscathed.

At Saturday’s final training session before NSW return from their Blue Mountains hideaway, the NSW halfback ran as confidently as any since entering pre-Origin camp under an injury cloud.

Hynes and the Blues then completed an opposed session with players from Penrith’s pathways teams.

Team staff later told AAP Hynes had pulled up fine and would play in the Origin series opener at Accor Stadium on June 5, provided he did not aggravate the injury that began troubling him in early May.

The news is a big boost for a Blues side that had been sweating on Hynes’ fitness to begin the week, and that had already lost halfback options Nathan Cleary, Mitch Moses and Adam Reynolds in the lead-up to their team announcement.

Josh Addo Carr will be out until August with a hamstring injury.

Canterbury football boss Phil Gould confirmed on Saturday morning that Addo-Carr , overlooked for Origin I, would miss between eight and 10 weeks after going off during Friday’s win at Newcastle.

Addo-Carr was substituted out of the Bulldogs’ 32-2 victory just after halftime, with scans on Saturday morning revealing a high-grade hamstring tear.

The injury blow comes after NSW coach Michael Maguire chose St George Illawarra flyer Zac Lomax and Penrith’s Brian To’o over Addo-Carr as wingers for the series opener on June 5.
