Mainland Premier League matches which are likely to be affected by the CECAFA Challenge Cup games are those from 11th to 13th rounds.

TFF Acting Secretary General, Wilfred Kidao, confirmed that the fixture will be disrupted but defended the move, saying the federation is not sure the CECAFA Challenge Cup will take this year.
He said after a two-year absence of the regional tournament, TFF is of the view that the event might also not take place this year.
"We have no choice but come up with a new fixture as from November 25 to December 9 many players will be with the national team in Kenya for CECAFA Challenge Cup games," he said.
Tanzania Premier League Board (TPLB) Chief Executive Officer, Boniface Wambura, had similar views on the issue, in which he said changes in the league's fixture at this stage is unavoidable.
However, the situation raises questions on communication between CECAFA and TFF.
The CECAFA Senior Challenge Cup brings together all senior national teams of the 13 member countries.
Uganda are the current champions, having won a record 14th title in Addis Ababa in December, 2015 after beating Rwanda 1-0 in the final.
