Murrayfield misery for Edinburgh
The visitors opened the scoring with a well-worked try inside 13 minutes as Pepito Elhorga cut in from the left flank and touch down near the posts.
Morrisson Faaletino added the conversion as Agen doubled their lead, surging through for a brilliant score. However, Faaletino was injured in the process and was helped off before Elhorga slotted the conversion.
