Dave Rennie came away from the Bulls win at Loftus feeling his side has made genuine progress — particularly in the scrum — but the buildup to next Saturday's Ellis Park test is now clouded by the fitness of Damian McKenzie. Rennie is less confident about McKenzie's availability than he is about Will Jordan and Cam Roigard, both of whom he expects to be ready. The bigger selection story, though, is Mo'unga: Rennie confirmed the flyhalf has arrived in South Africa 'excited and jumping out of his skin' but won't be considered for the first test after his extended Japan stint. He'll be earmarked for the Lions midweek fixture instead. Codie Taylor was candid that the Bulls 'tested us in patches' but acknowledged the Boks at Ellis Park will be a different proposition entirely — Rennie echoed that, noting 11 line breaks to one shows opportunities left on the field, and that the Springboks will 'come much harder defensively.'
