NSW has added Newcastle prop David Klemmer to the Blues' camp to replace suspended forward Tariq Sims ahead of the State of Origin decider next Wednesday night.

Klemmer was ruled out of game two after breaking his wrist during his strong game one performance.

Sims was originally in the squad, although he failed to overturn his dangerous contact charge at the judiciary on Tuesday night, paving the way for Klemmer's recall.

โ€œWeโ€™ve got the two best bookends in rugby league playing together in David Klemmer and Daniel Saifiti,โ€ Knights Director of Football Brian Canavan told newcastleknights.com.au.

โ€œItโ€™s the most high pressure game you can get and David will add balance to their pack.โ€
