James O’Connor will assume chief playmaking duties for Queensland, with incumbent No.10 Isaac Lucas dropped to the Reds’ bench to play the Lions in Johannesburg.

Lucas, 20, had shown promise at five-eighth in two Super Rugby pre-season wins and a close round-one loss to the Brumbies.

But he will be used as a finisher against the big-bodied Lions, with O’Connor shifting from inside centre and utility back Hamish Stewart recalled at No.12 for Sunday morning’s clash (12:05am).

Lock Izack Rodda will also earn his first start of the season after an off-season slowed by minor ankle surgery, while Alex Mafi will begin at hooker with Brandon Paenga-Amosa (ankle) out for up to eight weeks.

It will be O’Connor’s second start at No.10 for Queensland after calling the shots in his 2015 Reds debut and an ideal platform to push his case for a Wallabies berth in a position that remains up for grabs under new national coach Dave Rennie.

O’Connor played at No.12 in Friday’s loss in Canberra but finished at No.10 as the Reds coughed up a 10-point halftime lead to lose 27-24.

In a brutal three-week road trip to start the season, the Queensland outfit will move on to Argentina the following weekend to play the Jaguares, who thumped the Lions last weekend at home.

“They’ve (the Lions) been a good side over the past half decade, and it’ll be a tough contest,” Thorn said.

“Around the world trip; no other sport really does it, let alone a contact sport.

“So, if you can get a victory on this trip, you can call that a success.”
