Newcastle’s hopes of cementing their spot inside the NRL’s top eight have been dealt a huge blow with star centre Bradman Best ruled out with a calf injury. The Knights have had to count the cost of a rousing 30-6 victory over Brisbane last round, as Best emerged from the clash with a low-grade calf strain. Newcastle’s news comes after Canberra coach Ricky Stuart said their hopes of victory will rest on halfback Ethan Sanders’ kicking game. “It (kicking game) is important in every game, but when you’re playing in wet, slippery conditions it is important,” Stuart said. The Raiders welcome back centre Simi Sasagi from a hamstring strain as they look to rebound from a dismal 42-18 loss to Penrith last Saturday.
