Two players from last night's win are out of the touring party because of injuries received in the match against the Cheetahs.
Prop Pauliasi Manu left the field early with a calf injury while Ihaia West injured his ankle when he came on as a substitute for Piers Francis who had received an injury in the first half.
Manu has been replaced by Sione Mafileo, with Bryn Gatland re-joining the Blues as a replacement for West.
Gatland played three games for the Blues as a replacement, but exited the squad on Thursday before the late call to travel to South Africa. Francis was considered fit enough to travel with the touring party.
Blues squad: Ofa Tu'ungafasi, Charlie Faumuina, Sione Mafileo, Alex Hodgman; James Parsons, Hame Faiva, Joe Royal; Patrick Tuipulotu, Scott Scrafton, Gerard Cowley-Tuioti; Steven Luatua, Blake Gibson, Akira Ioane; Kara Pryor; Augustine Pulu, Sam Nock; Piers Francis, Bryn Gatland; TJ Faiane, Sonny-Bill Williams, George Moala, Matt Duffie, Rieko Ioane, Melani Nanai, Michael Collins.
