Stormers boss Allister Coetzee has made four changes to his starting line-up for Saturday's clash with the Crusaders in Christchurch.
The men from the Cape will take on the Crusaders without injured forwards, lock Rynhardt Elstadt and flanker Siya Kolisi, with the fit-again De Kock Steenkamp and Schalk Burger replacing them up front.
Elstadt has been ruled out of the tour with a shoulder injury and will be out of action for four to six weeks, but Kolisi has been given this week off and will come back into the selection frame next weekend.
"Rynhardt will see his specialist when he returns back home to Cape Town," Coetzee told the Stormers' official website.
"It's the same shoulder he had an operation on after last year, and the specialist here said it's quite badly inflamed. He will be out of action for four to six weeks and, for that reason, we have called up Jurie van Vuuren, who was part of the WP U21 side last year and can, like Rynhardt, play at number seven (flank) and number four (lock).
"We're fortunate to be able to rest Siya (at loose forward), where we have more depth, so hopefully this week off will see his AC Joint in a better condition next week."
Burger resumes the team vice-captaincy after missing last Friday's nailbiting 19-18 win over the Hurricanes at Newlands with a mild groin strain, whilst Steenkamp will make his first appearance of the season having also recovered from a groin injury of his own.
At scrum-half, in an unforced change, Nic Groom will earn his first start of 2014, whilst the loss of Elstadt and Manuel Carizza - the latter with a wrist injury from the 'Canes match - sees former WP U21 lock Ruan Botha earn a place on the bench on debut. Michael Rhodes, after two appearances from the bench this season, will start in place of Elstadt in the number four jersey.
Louis Schreuder will join Botha on the bench this week, along with experienced fly-half Peter Grant - who joined the team from Japan this week - and new wing signing Sailosi Tagicakibau, who joined the DHL Stormers from London Irish just a few days ago.
"Losi (Tagicakibau) has fitted in very well - in the changeroom after the Hurricanes match and in the gym this week," added Coetzee.
"We're looking forward to him making an impact in our first full (training) session tomorrow and come Saturday against the Crusaders.
"It's also good to have Peter Grant back.
"He's hungry to play again, after missing the majority of last year's campaign and having not played a lot in Japan.
"He's a good team man and will slot in well as always given his experience and standing in our environment."
