Richard de Carpentier will be handed his first start for Worcester at the weekend after signing a permanent contract with the club.
The 22-year-old back-rower, who has represented England at Sevens level, has impressed since he started training with the Warriors last month.
The former Leicester forward featured for Worcester Cavaliers in the Aviva A League defeat to Newcastle, and assistant head coach Nigel Redman confirmed that De Carpentier will start Saturday's LV= Cup clash against Scarlets.
"Richard has done incredibly well since joining us on trial in October," Redman said.
"He played out here against Newcastle and did exceptionally well and he's made a massive impact in training. He offers a lot of quality and players get on with him.
"Richard will start his first game for us on Saturday against Scarlets so he's got an opportunity to impress. He gives us another option in the back row and his presence will no doubt drive our standards upwards."
