Multiple reports say Stormers lock Van Heerden is called up to a Springboks squad following an injury to fellow player Moerat. The articles frame the selection in the context of squad depth: with the tight end of the department stretched, opportunities open up for fringe players as the international schedule moves toward its final matches. The reports also indicate that Van Heerden has been on the selection fringes and that his prospects rise because of the timing of Moerat’s latest setback and the availability window created by the remaining fixtures. While the coverage focuses on the call-up, it also underscores that Moerat’s injury is not a one-off, describing it as another injury that further affects team availability. Across the sources, there is agreement that the call-up is a direct consequence of Moerat being sidelined again and that Van Heerden’s promotion aligns with the Springboks’ current needs. Details beyond the call-up and the existence of Moerat’s injury are not expanded in the provided summaries.
