Brisbane and New South Wales centre James Roberts has been ruled out of the Broncos' clash with the Storm on Sunday, although coach Wayne Bennett confirmed to broncos.com.au his absence is just precautionary.
Roberts didn't train with the main squad on Saturday morning after playing for the Blues on Origin I, and will be left out of Brisbane's side on Sunday, with Tom Opacic to slot in next to Corey Oates and replace Roberts.
However, the Broncos' remaining Origin trio in Josh McGuire, Andrew McCullough and Anthony Milford all trained in their final session before Sunday's blockbuster clash, and look set to line up against Melbourne at AAMI Park.
