Bronco Corey Parker says Rabbitoh Isaac Luke will be a threat in blockbuster DANGERMAN: Issac Luke in action for the Rabbitohs. BRONCOS workhorse Corey Parker says it's not South Sydney's band of monsters that scare him most but rather an 89kg dummy-half terrier. Issac Luke, the New Zealand Test hooker, looks lost in the land of the giants when packing down next to Rabbitohs' behemoths Roy Asotasi (108kg), George Burgess (120kg), Sam Burgess (116kg) and Ben Te'o (106kg). Much of the focus for Friday night's round 8 blockbuster at Suncorp Stadium has been on the battle of the big men. Parker, however, insists Brisbane must remain extra cautious of the combative No.9. "He's probably one of the hookers in the comp that runs the most," Parker said of Luke. He's a very dangerous player, as we saw in that (trans-Tasman) Test match. With a game of footy it starts in the middle and he's the one who has got the ball most of the time so we'll concentrate on him and work it out off that. The clash with second-placed Souths looms as a welcome test for a Brisbane side teetering on a return to its best footy. Anthony Griffin's men have won three straight to surge to sixth on the ladder. "Now and then in footy you get a big challenge, - for us it's against Souths on Friday night," Parker said.
