"With George Moala out, we have adjusted our backline," Umaga said. "Orbyn has trained with us all season and has impressed us with his attitude and his skillset. He deserves his chance.
"Jordan is a big and fast winger. If we can do our work up front then we want to utilise his strength and speed to get us going forward."
It appears that Umaga has had a change of heart in terms of the best position for Ioane, still only 21, and the most talented player in his team.
At the start of the season Umaga said he felt Ioane's best position was on the wing where he could use his express pace and finishing power to the fullest in the outside channels.
Ioane has always wanted to play in the midfield, but has looked better at centre than at second-five, where he finds himself for the second time this season.
It is believed Umaga thinks that Ioane can easily make the switch between the Blues' midfield and the wing for the All Blacks, and there is no doubt the Blues look a better team when he has the ball in his hands, but, again, there are few better in the game than Ioane at beating players on the outside and it would be a waste of his talents to see him resorting to a crash-and-bash type game due to the heavy traffic he is running in.
In Ioane's favour is the fact that the Sunwolves are unlikely to bring the defensive line speed pressure of the New Zealand teams but the margins for error at this level are small and the Japanese team's Kiwi coach Jamie Joseph will know exactly where to target the Blues.
It is one more intriguing element to a match the Blues cannot afford to lose.
Ioane's positions this season: No11 v Highlanders, No11 v Chiefs, No13 v Lions, No13 v Stormers, No12 v Sharks, No13 v Chiefs, No12 v Sunwolves.
