London declined to field a team in the championship due to an outbreak of foot and mouth disease.
There were initially scheduled to host Mayo at Ruislip on the last Sunday of May but Connacht council decided to post phone the fixture a fortnight before the game was to take place.
The provincial championships in Munster, Leinster, Ulster and Connacht ran as usual on a "knock-out" basis.
But for the first time, these provincial games were then followed by the "Qualifier" system: The Leinster football championship reverts to normal just 1 Round pre to Quarter-finals.
Due to an outbreak of foot and mouth disease in the UK, London took no part in the Connacht Senior Football Championship in 2001.
