Both Smith and Perenara will be monitored at training today (thur) and a decision will be made on their fitness after.
If Perenara was to be ruled out, veteran Chris Smylie would start in the No 9 jumper with Tongan international Samisoni Fisilau coming on to the bench.
A Smith withdrawal would mean Leiua moves to centre and youngster Matt Proctor would come on to the wing to make his debut, while Hurricanes coach Mark Hammett would have to pick a new skipper with Victor Vito or Jeremy Thrush shaping as the likely contenders.
Hurricanes: Andre Taylor, Alapati Leiua/Matt Proctor, Conrad Smith (c)/Alapati Leiua, Tim Bateman, Julian Savea, Beauden Barrett, TJ Perenara /Chris Smylie; Victor Vito, Karl Lowe, Brad Shields, Jason Eaton, Jeremy Thrush, Ben May, Dane Coles, Ben Franks. Reserves: Ash Dixon, Reggie Goodes, Mark Reddish, Faifili Levave, Chris Smylie/Samisoni Fisilau, Tusi Pisi, Reynold Lee-Lo.
