Brandon Thomson will aim to make an impact on his Glasgow Warriors debut at Ulster on Saturday in the Guinness PRO12 (3pm, live on Sky Sports).
The 21-year-old joined the club last week on a short term deal from the Stormers in South Africa.
At the time of his arrival he was described as a stand-off, but he played centre for Stirling County against Watsonians last weekend in the BT Premiership and is now at 15, so he is clearly a versatile player.
Meanwhile, Pete Horne, who signed on until 2020 at Scotstoun early on Friday, returns from injury to start at stand-off at the Kingspan Stadium in Belfast.
On the bench, Namibian international Tjiuee Uanivi features for the first time since injuring his shoulder in the reverse fixture against Ulster back in September.
Hooker Corey Flynn is called up to the bench and Rory Hughes will cover the back-three.
Glasgow Warriors Head Coach Gregor Townsend said: “Brandon has integrated really well since his arrival and showed a good level of physicality while playing for Stirling County last weekend.
“He has a very good rugby brain and is a quick learner, and is relishing the opportunity to play for the club.
“It’s also great to be able to include Mark Bennett and Simone Favaro who both played Test match rugby last weekend. We will require everyone in our squad to play with huge commitment, effort and belief as we look to bounce back from last week’s disappointing result.”
