Stormers head coach Allister Coetzee has named a 27-man squad for their four match Super Rugby tour of Australia and New Zealand.
The Stormers have matches against the Crusaders, Chiefs, Brumbies and the Queensland Reds on this tour.
Centre Jean de Villiers will lead the squad abroad, a group that includes new Samoan star Sailosi Tagicakibau and the Japan-based Peter Grant, but excludes Argentinean lock Manuel Carizza.
Carizza suffered a wrist injury in last night's gusty 19-18 win over the Hurricanes at Newlands and will be out of action for eight weeks.
As a result, former WP Under-21 star Ruan Botha will travel with the squad, joining fit-again second row De Kock Steenkamp as one of the locking options in the 27-man group - alongside Rynhardt Elstadt and Michael Rhodes, who were both part of the 23-man squad last night.
Coach Coetzee commented: "It's very unfortunate for Manuel - he tore ligaments in his wrist and he will be out for two months.
"That said, Ruan has a great opportunity to get some game time after showing plenty of promise during our pre-season matches and, of course, it's great to have De Kock Steenkamp in the group too now that he's back to full fitness.
"We're happy with last night's victory. We know we can still improve in many areas, but we're happy to be heading abroad with that 'W' behind our name and we will build on that in what will be a very challenging tour."
The Stormers will depart for New Zealand on Sunday at lunch-time. The squad will fly - via Sydney - into Christchurch ahead of their opening tour match against the Crusaders next Saturday.
