There are no changes to the backline that started in the 48-36 victory against the Sigma Lions, as Western Province look to make it back-to-back home wins to start the campaign.

Theunissen is joined in the loose trio by skipper Nama Xaba and Keke Morabe, who makes his first start at No.8, with Simon Miller shifting to the second row.

Seasoned prop Ali Vermaak makes his return from injury on the replacements bench, with tighthead prop Corne Weilbach, hooker Jacques Goosen and loose forwards Jarrod Taylor and Roelof Smit (currently on trial) all in line to make their senior Western Province debut should they take the field.

Smit is a one-cap Springbok, while youngsters Weilbach, Taylor and Goosen are all part of SARU's Elite Player Development System via the SA Schools and Junior Springbok programmes.

Western Province Head Coach Jerome Paarwater said that his team is determined to back-up their opening win with an improved performance in this midweek clash.

"It has been a very short turnaround between games, but our combinations should be a little more settled, so hopefully we will see more cohesion.

"We have managed to keep some continuity in selection and the players are all keen to reward the fans who come out to support us with some good rugby," he said.

This north-south derby in the Mother City kicks off at 20:00
