Worcester Warriors duo Matt Cox and Greg King have agreed new deals with the Guinness Premiership side.
Back row Cox, 21, has signed a two-year extension while centre King, also 21, has agreed a new one-year contract.
Director of rugby Mike Ruddock said: "Matt is a former England Under-20 international and we're delighted he's signed as he has a big future ahead.
"Greg has also pledged his future to the club and we're delighted with that as he is an all-action centre."
Cox, who joined the Warriors when he was 15, appeared at open-side for England in their successful 2008 Under-20 Six Nations campaign.
He started all five games and scored two tries, he has also played for England Sevens.
He runs extremely hard and incredibly strongly at the game-line and he tackles above his weight and size

King made his full Premiership debut against Harlequins earlier this month.
Both players are products of the Warriors academy.
While Cox is currently sidelined following a shoulder operation, King may get a chance to impress in the European Challenge Cup semi-final against Bourgoin.
"He runs extremely hard and incredibly strongly at the game-line and he tackles above his weight and size," added Ruddock.
"Greg has been selected for the travelling party for the semi-final against Bourgoin.
"This highlights his potential and we expect great things from him next season."
