Josh Dugan will miss his second straight game with a hamstring injury while Tyson Frizell is in doubt with a rib problem.

Jason Nightingale filled in for Dugan with aplomb last week while Tariq Sims’ mid-game shift to cover for Frizell opened the door for an impressive debut from young-gun Hame Sele.

Jacob Host played the opening five games of the season from the bench before playing 80 minutes in the Intrust Super Premiership last week. He appears the man most likely to shift to the right edge should Frizell be a late withdrawal.

“The biggest thing we’ve had for a number of weeks now is we’re comfortable with anyone coming into our system,” McGregor said.

“When Tyson went off last week we didn’t have an edge back-rower on our bench which Jacob is and we saw Tariq step up.

“That’s the beauty of having Tariq there, he’s a middle but he’s who’s played a lot of edge in his career and he went straight on that edge and did a really good job for his footy team.

“Hame’s more of a middle player and he knows what’s required in the middle because that’s where he’s played all his career.

“Jacob’s learning both because he’s been more of an edge player during his career and to do that you need to play more minutes.

“The boys know what’s needed and the effort that’s needed in each position they play. That’s showing in the way they’re playing.”
