Worcester have signed Kai Horstmann from Harlequins on a two-year deal.
The 23-year-old No 8, who was relegated from the top flight with Quins, is the Warriors' seventh signing for next season.
Horstmann, who also had a trial with rugby league side London Broncos, had signed a three-year deal with Quins last season but was allowed to leave following their relegation.
"We saw him play quite a bit and were interested in him before he signed that threeyear deal this time last year," said Worcester coach John Brain. "He then didn't get many games last season because they were losing matches and they wanted to go for experience.
"We believe he has a lot to offer. He's athletic, quick, strong, aggressive and fits the profile of the player we are looking for. He's been very frustrated at his lack of opportunities at Quins but we believe that he is a player who has a very big future in the Premiership."
Hortsmann was a key figure in the Quins team that won the Zurich 'A' league in 2003-04. In the same campaign, he also played a part in England's squad during their IRB World Sevens series.
Worcester have already signed Shane Drahm, Andy Gomarsall, Chris Fortey, Nicolas Le Roux, Emiliano Bergamaschi and Ed O'Donoghue for next season as they build up to their second Premiership campaign.
