Injuries to Munster duo Simon Zebo and Kevin O'Byrne rule them out of action for the immediate future, while South African international Jaco Taute will join the province on a short-term loan.
It has been confirmed that Simon Zebo sustained a fractured rib in Munster's opening round victory at Parc y Scarlets last weekend. The international winger and full-back is expected to be sidelined for five weeks.
A further injury update confirmed Kevin O'Byrne will be unavailable for three months. The hooker who was a late replacement against Scarlets last Saturday sustained an elbow injury in the final minutes of the game.
In other news, Stormers and Western Province centre/full-back Jaco Taute joins the province on a four-month loan basis, subject to being granted a valid work permit.
The 25-year-old played for the Springboks on three occasions in 2012 and has made 50 Super Rugby appearances, having also represented the Lions.
Due to injuries to Francis Saili and Sammy Arnold, Director of Rugby Rassie Erasmus has called on the services of Taute to bolster the options available in midfield.
