2013 FKF Division One
The 2013 FKF Division One was the second season of FKF Division One and the Golden Jubilee second division season since it began in 1963. It began on 23 March and concluded on 21 December.
On 12 April, Murang'a United were suspended from participating in the league any further for the rest of the 2013 season and relegated to the Provincial League for missing three consecutive league games, against Brighter Stars, Maweni City and Kenya Revenue Authority. They were only allowed to participate in the Provincial League from the beginning of the 2014 season, and would not be replaced by any other team during the course of the season. As a result, all their results were nullified.
On 25 April, the Football Kenya Federation initially decided to slash the league to 20 teams for the 2014 season. For that to happen, it was decided that the league will consist of top 5 teams in each zone in addition to the two relegated Kenyan [Premier League|Premier League] teams. The remaining 28 teams will be relegated to FKF Division Two, which will begin next season, along with the 8 teams promoted from the Provincial League. However, due to the creation of the Kenyan National Super League on 10 July, it was decided that top 5 teams in each zone would be promoted to the new league along with the two relegated Premier League teams, while the remaining 28 teams along with 12 teams promoted from the Provincial League would form the new FKF Division One, which is to be the third-tier league from the beginning of the 2014 season.
Changes from last season
For this season, all Division One teams endorsed a decision to split both Zone A and Zone B into two groups of 12 teams each, increasing the total number of teams in the league to 48. It was decided that the first group from Zone A comprise teams from the Nairobi, Aberdares and Mount Kenya regions while the second group comprise teams from the Eastern, North and South Coast regions. The first group from Zone B is to comprise teams from the South Nyanza, Central and South Rift regions while the second group comprise teams from the North Nyanza, North Rift and Western regions. In the league phase, teams are to play each other only one and winners from each of the four groups will play the winners from the other group in their zone in a two-legged play-off tie to determine who gains promotion to the Kenyan Premier League for the following season.Outgrowers, who were to be relegated after finishing in 18th place in Zone B the previous season, were readmitted for reasons unknown.
