GARETH Owen is among ten players being released by the Ospreys.
Barry Davies, Chauncey O'Toole and Stefan Watermeyer are also on the list of out-of-contract players not being retained at the Liberty.
The departures come as the new Pro12 champions start looking ahead to next season.
Owen's exit comes a year after the youngster suffered what the Ospreys called a "substantial injury", one that saw him damage cruciate ligaments and undergo two-stage surgery.
He missed the entire 2011-12 campaign and so didn't have fresh opportunities to convince the region to offer him a new deal.
But he is not short of talent and it would be a surprise if he failed to find a new club or region as long as he can prove his fitness.
The 23-year-old Maesteg product played 50 games exactly for the Ospreys, scoring nine tries. When he burst onto the scene, he was feted as an international in the making, with then Ospreys director of coaching Scott Johnson comparing him to Gavin Henson. He was actually quicker than Henson, blessed with strength, a jolting hand-off and ability as a goal-kicker, but injuries hampered him and he found it hard to nail down a first-team spot.
Davies leaves after three years and 30 outings, bumps also not having helped his cause, but at 31 the one-cap former Scarlet will believe he still has plenty to offer.
It just hasn't worked out for O'Toole at the region, the Canadian World Cup player starting just two games, while Watermeyer was also lightly used after arriving from South Africa last winter.
He spent most of his time with Swansea RFC — an LV Cup outing and one Pro12 run-out being the sum of his on-pitch input at the Ospreys.
Matt Torrance, Dai Flanagan, Rory Pitman, Ben Thomas, Craig Cross and Ken Dowding are the others leaving the Liberty.
There are also departures at the Scarlets, with back-rower Mat Gilbert missing out on a new contract, while scrum-half Liam Davies's short-term deal isn't being extended.
