Johannesburg - Griquas coach Pote Human has made only two changes to his side for their Absa Currie Cup encounter against the Blue Bulls in Kimberley on Saturday.
Griquas will look to consolidate after beating the Sharks in Kimberley last week, but they will be without two key players in Ryno Barnes and Luzuko Vulindlu.
In the first change, hooker Matt Dobson comes in for captain Barnes.
Barnes has been suspended for one week following a citing for the use of an elbow in the game against the Sharks and is unavailable this weekend.
"It is disappointing that Ryno got suspended, but we have to shrug that off and focus on the game against the Bulls," Human said on Wednesday.
"Both Matt and Simon are good players who get the chance to prove their worth."
The coach added that flank Wesley Wilkins, who has been solid for Griquas since his return from a lengthy shoulder injury, would take over the captaincy this weekend.
"Wesley has impressed in every game thus far and has great leadership abilities, so we are looking to him to lead the side to victory," Human said.
"We know it is going to be tough. It was tough in the first round in Pretoria and nothing has changed since.
"The Bulls are at the bottom of the log and will want nothing less than a victory."
The only other change sees winger Jannie Boshoff replacing Luzuko Vulindlu, who has been ruled out with concussion.
