Cape Town - Jurie van Vuuren will don the No 4 jersey for the Stormers against the touring Blues in Saturday's Super Rugby match at Newlands.
The 21-year-old lock was a late inclusion in the Stormers' starting line-up following Jean Kleyn's failed fitness test on Thursday. Kleyn has a troublesome hamstring which usually requires about 14 days to mend.
Initially, Van Vuuren, who played well off the bench last week at Loftus Versfeld, found himself out of Saturday's 23-man match-day squad because it was decided that flank Siya Kolisi, back from injury, would be on the bench.
