Griffiths set for Ospreys return
The Ospreys have moved to sign prop Cai Griffiths from London Welsh.
Griffiths will return to the Welsh region on a one-year deal, the Ospreys announced.
Griffiths, 30, made more than 120 appearances for the Ospreys in two previous spells with them.
"It's good to be back where I consider my home region," Griffiths said.
" I had an amazing time with London Welsh last season and was part of a special experience, but I am really happy to be rejoining the Ospreys. I am looking forward to a fresh start and another challenge."
