Scrum half Matt Powell is handed the captaincy as Warriors aim for a perfect six out of six wins in the European Challenge Cup at Sixways on Saturday (kick-off 3pm).
Powell will lead the side with Pat Sanderson rested, his place going to James Collins, as Director of Rugby Mike Ruddock names a strong side for the visit of the Romanians.
Drew Hickey returns in the back row and Will Bowley is named in the second row in place of Craig Gillies who moves to the bench.
Ruddock retains the same back line that inflicted a bonus point defeat on Montauban in the last European outing.
Marcel Garvey, Netani Talei, Shaun Ruwers, Chris Horsman, Dominic Feaunati and Chris Fortey are all ruled out through injury while Kai Horstmann is rested.
