But physically Laumape is ready: "I've done all the hard work trying to get this groin right."
He will pair up with Willis Halaholo, but who wears which jersey is to be determined, and will be revealed at Thursday's team naming.
The Hurricanes' midfield options are stretched, with Vince Aso's calf still not ready, and with Matt Proctor nursing a minor hamstring twinge, which was due for a scan this afternoon.
Assistant coach John Plumtree did not rule out starting Proctor, but hamstrings do not come fully right in a week and it would be surely be something of a risk to start him. Pita Ahki, who was loaned to the All Blacks Sevens earlier in the season, could have been another option but he too is injured.
"Willis is the guy we have played the most in midfield this year and he has impressed us. Ngani is good too at 12. That's a bruising midfield we have there, and they might be pretty good together."
Plumtree knows there might be some long distance travel on Sunday, dependent on what transpires in the final round, though he joked that he hoped it wouldn't be to South Africa to alleviate pressure on his "old back."
"We've just talked about beating the Crusaders this week. We could really end up anywhere in the world, but we know where we are going on Saturday," says Plumtree.
