Background
The number of teams entering this year's competition remained the same, with Streatham & Mitcham (hardly a Lancashire club, but useful to make the numbers up) playing in their second (and what was to be their final) season. The total entrants remained at 14 and the same fixture format was retained.
There was no need for a bye in the first round, but there was still a "blank" or "dummy" fixture. The bye in the second round remained.
