Scotland and Edinburgh talisman Simon Taylor ended his injury hell with a try as the Gunners shot down high-flying Leinster by 41-33 at a chilly Murrayfield on Saturday night.
The number eight, making his first Celtic League appearance for a year after a serious knee injury, notched one of seven scores to help Edinburgh chalk up their fourth straight win.
Taylor could now find himself thrust straight back into RBS 6 Nations action in next week's wooden spoon clash with Italy.
Prop Ally Dickinson also grabbed a try double in an impressive attacking display by Frank Hadden's fired-up troops before a late Leinster rally set up a nervy climax.
