Rory Thornton will stay at Cardiff Blues next season after making his loan move permanent.
The 24-year second row spent the full 2018/19 season with the Blues on loan, making 20 appearances, and the two Regions have now agreed that Thornton will remain at the Arms Park.
Having come through the ranks of the Ospreys Academy, the former Bonymaen RFC youngster played 59 times for his home Region, injury restricting him to just four appearances in his final season before heading to Cardiff last summer.
Everybody at the Ospreys wishes Rory the very best for his future career.
