Overnight wrap

Canberra forward Neville Costigan has had his contrary conduct charge downgraded to a grade one at the Judiciary, resulting in just a one-game ban. Costigan pleaded guilty to a headbutt on Sydney Rooster Amos Roberts after the full time siren in Canberra's home win on Monday night.

But the Raiders have successfully argued the charge should be downgraded from level two to one because there wasn't enough evidence to suggest contact had been made. Costigan will miss Saturday night's clash with Cronulla but is free to return for round seven against Penrith.

Gold Coast's Luke Swain earlier had his striking charge downgraded, resulting in a one match ban.

The Australian and New Zealand camps will wind up preparations for tomorrow night's Anzac Test with a final training run at Suncorp Stadium today.

Neither side has any injury worries ahead of the clash with Kangaroos halfback Johnathan Thurston training strongly yesterday after being hampered by a knee injury earlier in the week.

Thurston says he is excited by the prospect of taking on the Kiwis while in the best form of his career, the North Queensland playmaker having made a blistering start to the season. His New Zealand counterpart Ben Roberts is facing an uphill battle to spark an upset win, the Kiwis having struggled in recent timers to win without inspirational number seven Stacey Jones who has now retired.

New Zealand has not won a Test since 2003 against either Australia or Great Britain without Jones in the line-up.
