Missile Thunder has pulled up well since winning a 950 metre Open Handicap in Cairns on Tuesday, but Wieland will make a late call whether to back him up.
Wieland is confident Perovic will be competitive again following his last start second to the Trevor and Peter Rowe-trained Major Artie in the Banana Cup at Innisfail on August 30.
The five-year-old son of Pierro claimed the Cairns Amateur Cup at his previous start at Cannon Park in the middle of August.
“He copped a bit of bad luck in the Banana Cup, but his Amateur Cup win in Cairns was very determined,” Wieland said.
