Stormers coach Allister Coetzee has named his side to take on the Bulls in Saturday's South African derby clash at Loftus, making four changes to his starting line-up that lost to the Sharks in Durban last weekend.

There are a several shake-ups in the forwards as Siya Kolisi returns after being withdrawn late last week before the clash with the Sharks.

Frans Malherbe gets a start at tighthead with Brok Harris moving to the bench. Deon Carstens packs down at loosehead as Steven Kitshoff has been called up to the South Africa u20 squad.

On the bench, Deon Fourie covers hooker and is in for Skara Ntubeni, who drops out of the match 22, while Quinn Roux has been handed jersey No. 18.

The bad news is that lock Andries Bekker has been ruled out for a minimum of five weeks, with a recurring back injury, and is replaced in the starting line-up by De Kock Steenkamp. Bekker will subsequently miss the Springbok Tests in June.

Stormers:

Gio Aplon, Gerhard van den Heever, Juan de Jongh, Jean de Villiers (c), Bryan Habana, Peter Grant, Dewaldt Duvenage, Jebb Sinclair, Rynhardt Elstadt, Siya Kolisi, De Kock Steenkamp, Eben Etzebeth, Frans Malherbe, Tiaan Liebenberg, Deon Carstens

Replacements: Deon Fourie, Brok Harris, Quinn Roux, Don Armand, Nick Fenton-Wells, Louis Schreuder, Burton Francis.
