George joins Warriors
Hooker Dan George has become Worcester's third signing from Gloucester for next term, as the Warriors pushed their total recruits to 15.
Rugby director Dean Ryan also sealed a deal for Leicester's loosehead prop Ryan Bower and handed Rob O'Donnell a new deal, as Worcester continue to remodel their squad.
The Sixways club face relegation to the Championship for next season, but have backed boss Ryan in a total squad clearout for his second campaign at the helm.
Welsh hooker George will join flanker Matt Cox and centre Ryan Mills in swapping Gloucester for the Warriors next term, with Cox returning to his first club.
"I am pleased with how the forward pack is shaping up ahead of next season," said Ryan, who still expects more changes to Worcester's squad.
"The arrival of Ryan and Dan, who both received international recognition in the early part of their career, will see us strengthen our options further.
"Rob has made the most of the opportunities he has been presented with this season and will continue to be an important part of the squad next season."
Former London Welsh hooker George joined Gloucester last summer, while 23-year-old Bower has had two loan stints at Nottingham since his Leicester debut in 2010.
Andries Pretorius from Cardiff Blues, Northampton's GJ Van Velze and wing duo Sam Smith and Tom Biggs represent four of Worcester's biggest signings for next term.
David Lemi, Chris Brooker, Josh Matavesi and Mariano Galarza will be high-profile departures, as former Gloucester boss Ryan continues his Sixways overhaul.
