There are just two changes to the backline that did duty in the clash with the Waratahs at DHL Newlands, with Johnny Kotze replacing Leolin Zas on the wing and Louis Schreuder getting a chance to start at scrumhalf with Nic Groom on the replacements bench.
In the front row hooker Scarra Ntubeni makes his first start since his return from injury, with Bongi Mbonambi set to make an impact in the second half.
Lock JD Schickerling comes back into the starting line-up as well, with Rynhardt Elstadt shifting to flank alongside Siya Kolisi and Nizaam Carr who moves to the back of the scrum.
Fleck said that after the bye his team are desperate to get back to winning ways, and will embrace the occasion in Singapore.“It is great for us to be here as the first DHL Stormers team to play in Singapore, but we have got a job to do and we are firmly focused on delivering an improved performance.
“The bye was good from a recovery point of view, but this phase of the competition is crucial for us and we have to hit the ground running against the Sunwolves,” he said.
