Worcester Warriors have made Bath lock forward Will Spencer their third signing for the 2016-17 season.
"Will is a hungry young second rower who will add vital competition to the pack," said Warriors director of rugby Dean Ryan.
"We're looking to help him realise his potential here at Sixways."
Spencer will be reunited with Bath team-mate Tom Heathcote, who is in his first season as Warriors' first-choice fly-half.
"From speaking to Dean and Tom, Worcester feels like the right place for me to further my career over the next few seasons," said Spencer. "There is a great young squad at the club. Hopefully, over time, we can achieve our goals and become a top Premiership side."
Meanwhile, Worcester look like they could be without first-choice scrum-half Jonny Arr for the rest of the season.
Arr was an unexpected absentee for Saturday's last-gasp 32-22 defeat at Wasps. But it has now emerged that he suffered a lateral media knee ligament injury in the 24-20 home defeat by Harlequins - and head coach Carl Hogg predicts he will be out for "three to four months at least".
Hey Big Spencer
After joining the Bath Academy in 2010, Spencer made the transition to Bath's first-team squad in 2014 and has since made 11 appearances.
The 6ft 7in forward spent a season on loan at London Welsh in 2013-14, playing a part in the Exiles' Championship-winning campaign.
His current contract with Worcester's Premiership rivals Bath was due to expire at the end of the 2015-16 season.
