Roberts leaves Ospreys for Bristol

The 29-year-old scrumhalf was out of contract at the Ospreys at the end of this season and, with Rhys Webb close to a return to action and the form of Brendon Leonard and Tom Habberfield, along with youngsters Matthew Aubrey and Reuben Morgan-Williams coming through the pathway, the region agreed to his early release in order to allow him to secure a contract until the end of 2016/17.

Roberts played 48 games for the Ospreys over two spells with his home region scoring three tries.
