Dual-code international Mat Rogers has expressed concerns over Maddi Levi's touted switch from rugby sevens to a potential Wallaroos debut.
The superstar Aussie speedster, who starred at the Paris Olympics last year, has been touted as a potential inclusion in the squad for this year's World Cup.
However, according to Rogers - who is Levi's manager - the decision would be a rushed one and he explained why officials need to be wary.

"I just don't think it's an appropriate step to take," he said on Stan Sport's Inside Line.
"I'm speaking from Maddi's perspective purely out of care for her. I don't want her to be set up to fail, and I think that's what's happening if they pursue it further this year.
"I would love to see nothing more than Maddi go over there and dominate, and Australia win the World Cup. I just think through injury and circumstance, it's going to be tough this year. I don't think she can [make the transition] in the time.
"She's not going to have enough game time. It's just unfair on her, and it's unfair on the squad to throw her in there and expect her to be a world-beater that she is in sevens.
"It's too much pressure."

Levi announced plans last year to play for the Queensland Reds to kickstart her transition, but that was pushed back after the 22-year-old suffered a broken hand.
She is expected to play in the LA Sevens tournament next month before shifting her attention to the 15-player format for the major tournament in August.
Rogers believes that parachuting sevens superstars such as Levi and Charlotte Caslick into the Wallaroos group could create "animosity" with other players.
"I just think we should let the sevens girls do what they do and then right before the World Cup just say to all sevens girls, you can go and play in the 15s and see if it doesn't create any animosity between the players," he said.
"That's what's happened this year, and it wasn't pretty. I'm being facetious there, but it's been unfair on the sevens girls and unfair on the 15s girls.
"I just know as a player, if I'm busting my butt in the 15s team, and all of a sudden you get these seven or eight girls want to play 15s … I would have been absolutely filthy."
