All Blacks coach Dave Rennie will make at least two changes to his starting team for the second test against the Springboks in Cape Town as his team chase a 2-0 lead in the series.The side to face the Springboks named on Thursday won't include lock Josh Lord and prop Ethan de Groot, who clashed heads late in the first half of the 33-16 win at Johannesburg last weekend.The pair are undergoing a mandatory 12-day stand-down under World Rugby's concussion protocols.De Groot's place at loosehead prop is likely to be taken by veteran front-rower George Bower, the 34-year-old's injection at Ellis Park midway through the opening test seemingly helping to solidify a shaky New Zealand scrum.Two-cap rookie prop Xavier Numia should take Bower's place on the bench despite clocking only limited minutes on tour.Xavier Numia.PhotosportThe 27-year-old Hurricanes powerhouse came off at halftime of the match against the Bulls in Pretoria because of concern over a tight Achilles tendon.He has since played 10 minutes off the bench late in Wednesday's win over the Lions, making a notable difference to the All Blacks scrum.Rennie may be considering two options to replace Lord.All Blacks head coach Dave Rennie.Chris Symes / www.photosport.nzBlues skipper Patrick Tuipuluotu came off early in the Lions match and could be thrust into the starting second row alongside Fabian Holland.Another option could be to add Tuipulotu to the reserves and promote flanker Simon Parker to a starting role on the side of the scrum.That would push Parker's Chiefs team-mate Tupou Vaa'i from blindside flanker into lock, where he has played most of his 48 tests.Rennie will be reluctant to veer far from the rest of his 23 who won at Ellis Park, with several other contenders having clocked up significant minutes in the midweek match against the Lions so unlikely to be physically primed.The Cape Town test starts at 3am on Sunday morning.Possible All Blacks teamDamian McKenzie, Will Jordan, Quinn Tupaea, Jordie Barrett, Josh Moorby, Ruben Love, Cam Roigard, Ardie Savea (capt), Luke Jacobson, Simon Parker, Fabian Holland, Tupou Vaa'i, Tyrel Lomax, Codie Taylor, George Bower.Reserves: Asafo Aumua, Xavier Numia, Fletcher Newell, Patrick Tuipulotu, Peter Lakai, Kyle Preston, Anton Lienert-Brown, Leroy Carter.
