Brisbane coach Ivan Henjak has urged match-winner Israel Folau to expand his attacking game against the Warriors at Suncorp Stadium on Sunday, encouraging the athletic centre to inject himself from anywhere on the field.

Folau scored two tries against Canberra in Brisbane's failed second half NRL comeback on Monday night.

But there was a feeling after the 22-14 loss that Folau could have been used more effectively and get even more involved in the game.

"I hope he does (inject himself more)," Henjak said.

"We obviously can't over-use him and we've got some other players we can go to, Izzy's not the only attacking option in our team.

"But I'd like to see him getting a little bit more ball and a little bit more involved and not just particularly in the centres either.

"It's something he can develop in his game. I think he has to take a little bit of responsibility there.

"While he's young, he's got 70-plus games under his belt and I think he needs to go finding the game a little bit more if it's not coming to him.

"I'm sure he wants to do more but unless you actually take yourself out of that comfort zone you don't learn it.

"He's aware of it and hopefully over the year we'll see a bit more of that from him."

Utility Alex Glenn trained at left centre on Saturday in the team's final run at Red Hill suggesting he may get a late promotion with youngster Gerard Beale, who's been solid without breaking the line, dropping to the bench.

Henjak confirmed promising back-rower Matt Gillett, who has been compared in style to former Manly international Nick Kosef, would make his starting debut for injured lock Corey Parker (knee) but was giving nothing away about any other last minute changes.

"I'm pretty happy with how they trained but we could come up with a surprise tomorrow before the game," he said.

"At this stage everything is as planned but there's a couple of things we'll have a look at tomorrow and what kind of day it is."

Henjak rates the Warriors highly after watching all their trials and their two NRL games this season.

"They've got some dangerous players and their attacking kicking has been pretty good," he said.

"They're still a very good second phase add-lib team and we're going to have to make sure we control that aspect.

With former Broncos and Sharks halfback Brett Seymour still on the sidelines, Brisbane are likely to target Warriors halves James Maloney and another ex-Bronco Joel Moon.

"I think no matter what team you play they (halves) are the position in the opposition that you have to get some pressure on the fifth and last (tackles) because they've got some dangerous players that they kick to in (Manu) Vatuvei and young (Kevin) Locke," Henjak said.

"They've also got some other big guys like Simon Mannering and (Sam) Rapira who are dangerous close to the line, so you've got to cut their time down on fifth and last plays."
