Griquas coach Pote Human was forced to change his victorious team for the Currie Cup encounter with the Sharks on Friday.
Veteran centre JP Nel, dislocated his finger in the 37-21 win over the Golden Lions last week, underwent surgery this week.
He will be sidelined for four weeks and won't feature again this season.
Another seasoned campaigner, Walter Venter, has been named to start alongside Jean Stemmet in the Griquas midfield for the trip to Durban.
Richard Lawson comes onto the bench in place of Venter.
There is one other change on the bench, where loose forward Wesley Wilkins - who has recovered from his injury - replaces Jaco Nepgen.
Griquas need to win to book their place in the Currie Cup play-offs for the first time in more than a decade.
Griquas: 15 Willie le Roux, 14 Jannie Boshoff, 13 Jean Stemmet, 12 Walter Venter, 11 Rocco Jansen, 10 Francois Brummer, 9 Marnus Hugo, 8 Leon Karemaker, 7 Justin Downey, 6 Marnus Schoeman, 5 Martin Muller, 4 Rynard Landman, 3 Lourens Adriaanse, 2 Ryno Barnes (captain), 1 Steph Roberts.
