Worcester have signed Matt Cox and Ryan Mills from Gloucester, with the duo due to join the Warriors in the summer.
Cox, 25, graduated from Worcester's academy in 2007 and spent three years as a first-team player before moving to Gloucester in 2010.
The back-row forward, who has represented England at U18, U19 and U20 level, went on to make 58 appearances for the Cherry and Whites.
Cox will be joined at Sixways by team-mate Mills, who will make the short journey north after four years at Kingsholm.
The centre, who can also play at fly-half, has scored 35 points in 20 games for Nigel Davies' side since graduating from Hartpury College.
He previously spent 12 years with Exeter Chiefs from the age of five before cementing a place in the England U18 and U20 squads.
Mills was part of the Under 20 Junior World Cup and Six Nations squads in 2011 and 2012, helping his country to Grand Slam success in the latter three years ago.
He said: "I have thoroughly enjoyed my time at Gloucester. It's been unfortunate, however, that I haven't played as much as I would have liked due to a number of injuries."
Worcester director of rugby Ryan said: "It is an extremely positive development for the club to secure the services of in-demand players such as Matt and Ryan who have made the choice to join us at Sixways."
