NSW centre Michael Jennings has been entrusted with the toughest job in rugby league, trying to stop a rampant Greg Inglis when the Blues attempt to avoid an Origin series cleansweep at Suncorp Stadium on Wednesday night.

The Blues finally unveiled their new backline at training on Friday with Jennings lining up at right centre where he will mark Inglis.

Jennings was slated to start the match at left centre but when another left centre in Bulldogs flyer Josh Morris was brought into the squad to replace the injured Jamie Lyon, something had to give.

So Jennings was switched over to the right, where he will be hoping to rekindle the successful partnership he formed with winger David Williams when they were paired for City Origin back in early May.

It's a daunting assignment for Jennings, who only last weekend returned for Penrith from a calf injury sustained in the opening game of the series, Inglis having been the best player on the paddock in Origin II until knocked out by a Trent Barrett swinging arm.

Much has been made of the Maroons seeking retribution for the Barrett hit, but Inglis has made it known he intends to exact his revenge on the scoreboard.

Jennings, though, is far from worried about going up against Inglis, the 21-year-old just thankful to get a second chance.

"The players that played in game two, I thought they did their job so I didn't think I was going to get another opportunity," Jennings said of his injury-forced absence.

"I'm grateful for it, just to get this opportunity."

Not only has Jennings an opportunity, he is seen as the prize weapon of the Blues backline just waiting to be unleashed.

He made several half breaks in game one without quite busting the line and it was coach Craig Bellamy's desire to get him more early ball that saw five-eighth Trent Barrett recalled for game two of the series.

They never got to get together thanks to Jennings' dodgy calf and it appears they will get few opportunities to combine in game three in Brisbane with Barrett almost exclusively working with the left side attack of Morris and Jarryd Hayne.

That left Brett Kimmorley to look after the right, Jennings somewhat chuffed to learn about Bellamy's desire to get him more involved.

"I'm stoked to even think that they would want them on the team to help me, but I guess that's the way the coach sees it," Jennings said.

"He wants to get me more ball and use my speed I guess."

Jennings left any doubts over his fitness with a scorching return for the Panthers at the weekend, a hat-trick and an assist for the match-winning try leaving selectors with little choice but to reinstate him.

The same couldn't be said of some of his Blues teammates on Friday with Kurt Gidley (ribs) and Ben Creagh (ankle) both sitting out a vigorous two-hour-plus training session.

Neither is believed to be in any doubt to play on Wednesday with Creagh likely to train in Saturday's opposed session, while Bulldogs veteran Luke Patten is again likely to deputise for Gidley.
