Cape Town - Stormers head coach Robbie Fleck revealed that Scotland centre Huw Jones trained with the side earlier this week.
Jones has been on Six Nations duty throughout the Stormers' pre-season but returned to Cape Town and took part in Tuesday's training session.
An injury crisis in midfield has seen the Stormers lose Damian de Allende and Juan de Jongh, tempting Fleck to select Jones for this weekend's match against the Jaguares.
But Fleck admitted that the Scotland international's focus was on next weekend's Calcutta Cup clash with England at Twickenham.
"Huw trained on Tuesday, but we decided that in terms of continuity of selection, we went with Dan Kriel‚" Fleck Fleck told the TimesLIVE website.
"Huw has a massive game against England next week‚ which is a decider. To be fair to him‚ his mind is on that game. There has been no pressure from Scotland. We have been in constant communication with them."
In other changes to the Stormers side, Sikhumbuzo Notshe comes into the starting line-up, with Nizaam Carr on the bench.
The only other change to the match-day 23 that did duty in the 37-24 victory against the Bulls last week sees World Sevens Player of the Year Seabelo Senatla named as a replacement, putting him in line to earn his first Stormers cap since 2015.
Fleck told the Stormers’ official website that he would like to see his team build on their performance last week against what is a very competitive Jaguares team.
“The win last week was encouraging, but there is still much we can improve on and we will be tested against a Jaguares team full of internationals,” he said.
Kick-off for Saturday’s match is scheduled for 17:15.
