The structure for competitive Gaelic football in Tyrone is based on league and championship competitions. Modern tradition strongly links league and championship ranking together; winning a respective championship also gets you promoted in the league regardless of where you finish in the latter, while the league can see your championship status being upgraded or downgraded. Competitions in Tyrone are organized in the following manner. Senior Regardless of wherever a team plays in the county Senior, Intermediate or Junior football championship, the main or first team in all clubs are regarded as the senior team. There are current 49 teams from 48 clubs competing in this grade (Errigal Ciarán have a third team that competes in Division 3). In the 2007 season the All-county league (ACL) is split into four divisions of 12 teams each except for Division 3 which has 13 teams. The divisions in ranking order, with the highest one first, are Division 1A, Division 1B, Division 2 and Division 3. Teams that compete in Divisions 1A & 1B compete in the Senior Championship, Division 2 teams compete in the Intermediate Championship and Division 3 teams play for the Junior Championship. Each team plays each other on a double round-robin, giving sides 22 league games or 24 in Division 3. From 2008 the ACL will be split into three divisions, with the finishing places from the 2007 league determining which of the three divisions each team will play in. Divisions 1 & 2 will each have 16 teams with the remainder in Division 3. The league will be played on a single round basis giving teams 15 games a season. The Senior, Intermediate and Junior Championships are all played on a straight knockout-basis, usually commencing in May and finishing in September or October. Reserve All clubs, except Errigal Ciaran's third team, have a corresponding reserve team that acts as a second string below their senior team. These teams compete in the same divisions as their senior team, with most matches taking place on the same day before the corresponding senior fixture. The Reserve Championships take place in a similar fashion to their senior teams, though they are called instead the Division 1, Division 2 and Division 3 Reserve Championships. There is no promotion or relegation between reserve leagues, it is dependent on how successful their senior team does in the same year. Therefore, unlike their corresponding senior team, it
