Format
Current format

The senior championship reverted to a straight knock out in 2016 and continues with minor alterations. At the end of each round, a draw was held to determine the fixtures in the next round.

In Derry, relegation or promotion within the league system determines which championship clubs compete in – Division 1 teams compete in the senior championship, Division 2 teams in the intermediate championship and Division 3 teams in the junior championship.

Previous Formats

A back-door format was used from 2009 to 2015. Four initial ‘round-robin’ groups progressing to an eight team straight knockout were used in seasons 2007 and 2008.
