Brisbane NRL coach Anthony Griffin has devised a game plan he hopes will keep South Sydney dangerman Greg Inglis in check in Friday night’s NRL clash in Perth.

The Broncos wrapped up preparations ahead of their long-trip to Western Australia on Thursday with their focus very much on containing Inglis.

Souths coach Michael Maguire shifted Inglis from the centres to fullback against Penrith last week and the giant international ran riot with the Rabbitohs belting the Panthers 40-24.

Griffin admitted he’d rather Inglis played in his usual position.

“I’d prefer he was in the centres because he gets a lot of early clean ball now and you saw what he did to Penrith last week,” Griffin said.

“We’ll just have to be very good with our kick-chase and our edge defence when he comes into the line.”

Griffin dismissed talk of young winger Dane Gagai, who extended his contract by two years this week, being a late addition to the 17-man squad.

Gagai will travel to Perth but, unless there’s is an unexpected injury, will not play.

“There’s a rumour going around he’s playing but I will have to check that one out myself,” Griffin said.

There was some suggestion Gagai could replace winger Gerard Beale, who failed to take up Brisbane’s contract offer this week and will be leaving the club for St George Illawarra in 2013.

“Gerard will be selected on his merits and what he does in 2012,” he said.

Brisbane will be out to avenge last year’s loss to Souths in Perth, a match played in atrocious wet conditions.
