Siya Kolisi's fitness remains uncertain as South Africa prepares for a crucial Rugby Championship clash against New Zealand on Saturday, following a facial injury sustained during their recent match. The Springboks have delayed their team announcement from Tuesday to Thursday as they assess Kolisi's condition, with reports suggesting a potential fractured cheekbone from a tackle by Sam Cane. Springbok scrum coach Daan Human emphasized the importance of Kolisi's leadership and performance, while also noting the depth within the squad if he cannot play. The absence of Kolisi could impact the Springboks' strategy, as they aim to secure their first Rugby Championship title since 2019, leading the table with 14 points. Additionally, winger Kurt-Lee Arendse is also likely out due to injury, compounding the team's challenges ahead of the match. The Springboks are confident but recognize the need for improvement against a formidable All Blacks side.
