Current format The senior championship reverted to straight knock-out in 2016 and the format continues with some minor alterations. If the score is level at the end of the normal sixty minutes, the match is replayed. If the replay is also level  at the end of normal time, two ten minutes halves are played each way. At the end (or close to the end) of each round, a random draw is held to determine the fixtures in the next round. In Derry, relegation or promotion within the league system determines which championship a club competes in – Division 1 teams compete in the senior championship, Division 2 teams in the intermediate championship and Division 3 teams in the junior championship. 2018 was the last year for this league format as the adult football leagues in Derry were restructured to Division 1A - 12 teams , Division 1B - 12 teams and Division 2 - 14 teams (previously there were 16 teams in Division 1, 14 teams in Division 2 and 8 teams in Division 3) for the start of the 2019 season. Five teams were relegated from the 2018 Division 1 to the new 2019 Division 1B (see section 'Relegations and promotions in 2018' below for details). The 2019 senior championship was competed for by the top 15 teams in the 2018 Division 1 and Banagher, the winners of the 2018 Division 2. Claudy, who finished 16th in 2018, were relegated to the 2019 intermediate football championship . Previous Formats A back-door format was used from 2009 to 2015. Four initial ‘round-robin’ groups of four teams with the top two teams in each group progressing to the four knockout quarter-finals were used in seasons 2007 and 2008.
