Colby stand in the way of St John's completing the football season with the second tier treble this afternoon (Saturday).
St John's made it 24 straight wins in a 100 per cent league campaign, when they won 9-1 at Foxdale on Tuesday night.
They comprehensively beat today's Paul Henry Gold Cup final opponents Colby 8-1 in the Woods Cup final on Good Friday, and go into today's encounter at Peel as big favourites.
Colby finished fourth in Division Two but were 29 points behind St John's in the final table.
The southerners know the odds are stacked against them, but will rely on a good blend of experience and youthful exuberance to try and pull off a shock result.
The game at Peel kicks off at 2.30pm.
