Jean at 13 for WP
Jean de Villiers will start at outside centre for Western Province in Saturday's Currie Cup semi-final against the Golden Lions at Newlands.
The Springbok captain De Villiers replaces Michael van der Spuy in the only change to the WP line-up that defeated the Sharks by 17-13 in Durban last Saturday - a result which sealed a top-of-the-log finish for the reigning champions.
Deon Fourie, who start at openside flank, retains the captaincy however.
Van der Spuy drops out of the matchday 22 altogether, with another Springbok centre, Juan de Jongh, joining the replacements bench after pulling out of the team at the 11th hour last weekend with a hamstring injury.
Province are the only unbeaten team heading into the 2013 Currie Cup play-offs. They have also suffered just one defeat at Newlands this entire year - in the guise of the Stormers - and will be hoping to advance to a first home final since 2001.
"To underestimate the Golden Lions would be the biggest mistake ever. This Lions team knows how to win," WP coach Allister Coetzee told wprugby.com.
"They actually played poorly and won against Griquas last weekend. They came from behind and in the second half they've been the side that up the intensity and put a lot of teams under pressure, so I'm under no illusions that we have to be careful and not underestimate the Lions."
