Du Preez twins start for Sharks
The Sharks are on a two-match French tour that will also see them face Toulouse net Thursday.
The team, captained by flyhalf Pat Lambie, has a very solid look about it – with a host of Springboks in the starting line-up.
However, the selection of the Du Preez twins will steal the headlines.
"It's a great opportunity for youngsters such as Jean-Luc and Daniel du Preez to get their first start in the Super Rugby squad," Director of Rugby Gary Gold said.
"This weekend's game is a nice opportunity to test ourselves and see how far we've come, with what's been quite a lengthy pre-season.
"We've selected a strong side against what should be a good Toulon team.
"The guys are really excited and I know that we will be a bit rusty in comparison to a Toulon team that are mid-season and have been playing together for a few months, but's that the type of challenge we wanted."
