The Ospreys failed to qualify for the quarter-finals of the Heineken Cup, and Llewellyn is the first casualty as the Ospreys 'redefine thier sqaud' for the next season.
Llewellyn is Wales' most capped forward with 83 caps, seven of which were earned as captain of the Welsh team. He played over 300 games for Neath before joining the Ospreys and captained Neath for a record 7 seasons from his debut at the club as a 19 year old in the 1988/89 season.
It is unlikely that, with Six Nations training set to start soon, Llewellyn will be making any decisions soon on the new direction he wants to take, but it is understood this will involve remaining as an active player of rugby for the foreseeable future.
The Ospreys also announced today they are releasing flanker Gavin Thomas onto the transfer market, as the club begins a process of redefining its squad ahead of next season
