Nat Saumi's last game in charge of Plymouth Albion ended in victory at already relegated Doncaster.
Albion dominated the first half and led 19-5 at the break courtesy of tries from Luke Cowan-Dickie, Ruairi Cushion and a penalty try.
Tries from Chris Hallam, Dougie Flockhart and Adam Kettle either side of the break pulled the knights back into the game.
But Albion wrapped up victory with a bonus-point try from Paul Rowley.
After 17 years in south west rugby - the last 10 at Albion - Saumi is returning to Fiji.
