The Gabba ground is bracing itself for the cyclone to make its forecast way down the Queensland coast, with the anticipated ensuing deluge of rain already putting the match in peril.

In a worrying build-up, the Australian team have been forced to hold training sessions indoors while the storm has left the four-time world champions scratching their heads over the potential make-up of their team.

"All the weather has done has delayed the naming of the team," Haddin said on Thursday. "We are not sure what we are going to get when we pull the covers up." (Also read: Coach Lehmann confirms Clarke's return in match vs Bangladesh)

The wild weather has also led to speculation that Cummins will join Starc, Hazlewood and Johnson, who all played in the opening 111-run win over England at Melbourne last weekend, in the starting side against Bangladesh.

"Yeah, there is a possibility," Haddin said. "If there wasn't any weather around that probably would have been slim.

"But it's hard to give you a team or what we are thinking because we are so unsure on what is going to happen with the weather and when they pull the covers up."

The only certainty, admitted Haddin, is that skipper Michael Clarke will play in the game having missed the England match after failing to shake-off the lingering after-effects of his long-term hamstring problems.

"This was the plan for Michael all along, for him to be right for this game," said Haddin.

Stand-in skipper George Bailey is expected to make way for Clarke despite calls for all-rounder Shane Watson to be dropped after his first ball duck in the win over England.
