HE may only be 27 years old but Parramatta second rower Nathan Hindmarsh has been cut down by arthritis in his feet. Hindmarsh has only just resumed running, his off-season training consisting mainly of swimming. He has yet to sidestep at training. The condition will almost certainly prevent Hindmarsh from playing in Saturday's match against New Zealand Warriors at Mount Smart Stadium. Hindmarsh has not played a trial - his last match being Australia's golden-point win over New Zealand in November's Tri-Nations final. He had surgery straight after the Tri-Nations and continues to recover. Hindmarsh's recovery is on schedule but given his lack of pre-season training, club officials will be reluctant to risk him against the Warriors, given the gruelling length of an NRL season. "He will almost certainly be unavailable this weekend," Parramatta coach Michael Hagan said. "We have to be careful with Nathan's rehab. He has only been running four weeks but hasn't caught a football yet or stepped off his feet yet." Asked about players so young having arthritis, Hagan said: "It is wear and tear on the joints. Danny Buderus had something similar." Hindmarsh's injury will not be long term. He could be back in round two, if not, certainly round three.
