Sam Underhill will come into contention for an England call-up after the Ospreys flanker signed a three-year deal to join Bath at the end of the season.
The United States-born back-rower moved to Ospreys from Gloucester in 2015, but will return to England ahead of the 2017/18 season to link up with Todd Blackadder's side.
Eddie Jones has been unable to select the 20-year-old due to the Rugby Football Union policy of not picking players based outside of England, but Underhill could now be in line for a call-up for the tour of Argentina in June.
Former England Under-18 captain Underhill said: "I'm really excited to be moving to Bath. There is a brilliant environment at the club, and some very talented players, both of which were a huge incentive in joining for me.
"They have a world-class coaching set-up, who I know will help me develop into the best player I can possibly be.
"I've enjoyed a really good couple of seasons at Ospreys, and would like to thank everyone who has helped make this move possible, and the fantastic support I've received throughout my time in South Wales."
Blackadder said: "We're really looking forward to Sam joining us. We've got a really strong contingent of backrows in the squad, and Sam's addition will boost that even further.
"He's a very talented young player, and we can't wait to see him develop even more over the coming seasons."
