London Irish have signed Isaac Miller from fellow Premiership side Worcester Warriors.
Hooker Miller joins the Exiles after spending four seasons at Sixways, where he made 50 appearances.
The 28-year-old is a former Scotland Under-20s and London Scottish player.
“Isaac has built up a wealth of experience in both the Premiership and Championship and I’m sure he will have a positive impact,” said London Irish director of rugby Declan Kidney.
Miller is the eighth addition to the Exiles squad as they look to improve upon last season’s eighth-place finish in the Premiership.
