Jonathan Thomas will lead his side into a new era after being named Worcester captain for the 2013/14 campaign.
Thomas, who joined the club from Welsh region Ospreys, has been handed the captain's armband after impressing since his arrival.
Thomas captained the side in Warriors' opening pre-season friendly victory against Rotherham Titans and led the side again on Saturday for the visit to his former club.
Vastly experienced back-row Thomas will make his competitive Warriors debut when the season gets underway at Leicester Tigers next month.
During a decade at Ospreys, the 30-year-old helped his side to two RaboDirect PRO12 titles and two second-place finishes. He played 188 matches for the club - including 52 Heineken Cup appearances.
The 6ft 5in flanker, who can also operate at number eight or lock, has impressed on the international stage - winning 67 caps for Wales.
"Jonathan has been an asset to Warriors since he joined us in the summer, both in his performances on the pitch and also in the qualities he demonstrates off the pitch," said Worcester director of rugby, Dean Ryan.
"He's a strong leader who understands the game and his past experience with Wales and Ospreys will be important in building the future here at Sixways."
