Cape Town — Stormers lock Eben Etzebeth will miss the encounter with the Hurricanes in Wellington on Saturday due to concussion.
Etzebeth took a knock to the head in the 35-8 win against the Jaguares at Newlands last week which saw him go off for a Head Impact Assessment (HIA) and spend the rest of the game on the sidelines.
The experienced second-rower was named in the Stormers starting line-up on Thursday, after passing a number of standard tests in the week, but has subsequently been ruled out.
As a result JD Schickerling comes into the starting line-up to form a lock partnership with Chris van Zyl, with Salmaan Moerat on the bench.
Stormers coach Robbie Fleck said that the safety of the players will always come first.
"We were hopeful that Eben would be fit to play against the Hurricanes, but unfortunately he did not come through some of the tests later in the week, so we made the call to give him another week to recover fully.
"JD Schickerling has been in great form this season and we are also excited about what Salmaan Moerat will do with this opportunity," he said.
Saturday's clash is scheduled for 08:35 (SA time).
