While Folau's performance drew widespread acclaim, coach Sir John Kirwan said he had not seen any of the action.
"I'm only concerned in what we are about at this stage," he said yesterday. "These games are about what we want to do."
The Blues travelled to Toowoomba where they lost 35-41 to the Reds in their first hit-out.
"We have a lot to work on but it was nice to get some game time together and work on the direction we want to go. We did enough to show we are on the right track but there is still heaps to work on."
Midfield back Jackson Willison damaged a thigh muscle and will not play this week. However, the Blues hope George Moala will return for the first time since breaking his leg in September and that Liaki Moli is over his hamstring twinge.
Others expected to return to work after missing the opening game are captain Ali Williams, Culum Retallick, Chris Noakes, Rene Ranger and Charlie Faumuina. Halfback Piri Weepu will open his trial work against the Highlanders. Anthony Boric has started contact work at training.
