The lock’s club form soon saw him pick up international accolades and after being named in the Scotland squad ahead of the 2015 Six Nations, he made his full international debut from the bench against Italy in March 2015.
Toolis made his 50th appearance for the club in the 11-try 36-35 European Challenge Cup win over Harlequins at BT Murrayfield in October 2016, while he continued to see game time on the international stage.
The lock has forged a solid second-row partnership with Scotland teammate Grant Gilchrist in recent years and today commits his immediate future to Edinburgh Rugby.
